Description

Real-time data updating method and device, electronic equipment and storage medium

Technical Field

The embodiment of the invention relates to the technical field of data processing, in particular to a real-time data updating method and device, electronic equipment and a storage medium.

Background

With the high-speed development of internet application, the characteristics of massive data, large flow, high concurrency and the like of the internet application are more prominent and obvious, and the traditional database architecture in a master-slave mode cannot meet the high-speed development of internet application services. In order to improve the performance of the system, a data slicing architecture is adopted in many IT (Internet Technology) system architecture designs. The data slicing is to slice data according to a slicing key (such as a client number or an organization number in the financial field), and store the data of different slices independently, for example, each slice data is stored in a database.

In the data processing architecture, when a data query request is processed, data query which can belong to the same fragment is very efficient, but joint query across data fragments is difficult to realize, and query efficiency is low. In the related technology, in order to improve the efficiency of data query across data shards, the proposed solution is to convert all shard database data and then synchronize the processed data to an aggregated database for table-linked query, where the aggregated database may be implemented by using a large data storage technology.

In the process of implementing the invention, the inventor finds that the prior art has the following defects: in the process of data synchronization updating of the aggregated database, since the aggregated database is used for synchronizing data updating of different source fragment data, even if the aggregated database has a global transaction control function on the source fragment database, the data updating cannot be performed according to a local transaction submission sequence of the source fragment database. That is, the aggregated database cannot maintain the ordering of the source database updates.

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Example one

Fig. 1 is a flowchart of a real-time data updating method according to an embodiment of the present invention, where this embodiment is applicable to a case where distributed transaction data is updated synchronously in a chronological order through a data processing server, a message queue and a cache queue, and the method may be executed by a real-time data updating apparatus configured in the data processing server, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in an electronic device, where the electronic device may be a server device, and is used in cooperation with a global transaction processor and a local transaction processor. Accordingly, as shown in fig. 1, the method comprises the following operations:

s110, polling the target queue according to the data mark of the cache queue to sequentially obtain distributed transaction processing data of each local transaction number under the global transaction number corresponding to the real-time data updating operation; wherein the target queue comprises a message queue and/or a buffer queue.

The data processing server may be used as a data aggregator to consume data in the message queue, implement aggregation operation on data submitted in the distributed Transaction, and may establish a communication connection with a Global Transaction Service (GTS) to perform interaction. The buffer queue data flag may be used to identify whether buffered data is present in the buffer queue. The real-time data update operation may be a business operation performed on the data in real-time. Alternatively, the user may perform a business operation by executing a business operation at the system front end of the real-time data update system, which may cause real-time update of the data stored in the database, and thus may act as a real-time data update operation. The global transaction number may be one transaction number generated each time the front-end system initiates a complete real-time data update operation. That is, one global transaction number may correspond to one real-time data update operation. The local transaction number may be a number corresponding to each distributed transaction data. It should be noted that one global transaction number may correspondingly include a plurality of local transaction numbers, and each local transaction number included in one global transaction number has a temporal order. The distributed transaction data may be data resulting from processing of a distributed transaction by a local transaction processor. The distributed transaction may refer to that a participant of the transaction, a server supporting the transaction, a resource server, and a transaction manager are respectively located on different node devices of different distributed systems, and may also be referred to as a local transaction. The local transaction processor may then be a processor running in a distributed database. The message queue may be responsible for receiving distributed transaction data submitted by the local transaction processor after completing the distributed transaction for consumption by the data processing server. The cache queue may be responsible for caching the distributed transaction data obtained from the message queue for subsequent use by the data processing server.

In the embodiment of the present invention, when the data processing server determines that the distributed transaction data of the real-time data update operation needs to be updated in real time, the distributed transaction data of each local transaction number under the global transaction number corresponding to the real-time data update operation may be sequentially obtained by polling the message queue and/or the cache queue. The distributed transaction processing data of each local transaction number under the global transaction number corresponding to the real-time data update operation may be obtained sequentially according to a time sequence between the distributed transaction processing data.

In an optional embodiment of the present invention, the polling the target queue according to the data flag of the cache queue to sequentially obtain the distributed transaction data of each local transaction number under the global transaction number corresponding to the real-time data update operation may include: polling the message queue to obtain distributed transaction processing data of the current target local transaction number according to the transaction processing sequence under the condition that the mark data of the data mark of the cache queue is determined to be first mark data; polling the message queue and the cache queue to obtain distributed transaction processing data of the current target local transaction number according to the transaction processing sequence under the condition that the mark data of the cache queue data mark is determined to be second mark data; and when the distributed transaction processing data of the current local transaction number acquired by polling the target queue is not the distributed transaction processing data of the current target local transaction number, the distributed transaction processing data of the current local transaction number is used for caching into the cache queue.

The first flag data may be used to identify data that is not buffered in the buffer queue, for example, the first flag data may take a false value. Accordingly, the second flag data may be used to identify that there is data buffered in the buffer queue, for example, the second flag data may take the value of true. Optionally, the flag data of the buffer queue data flag of the buffer queue may be the first flag data by default. The current target local transaction number may be a local transaction number currently required to be processed as determined by the chronological order of the local transaction numbers. For example, assume that each local transaction number is specifically 001, 002, 003. If the data processing server processes the distributed transaction data for the first time, the current target local transaction number may be 001, that is, the distributed transaction data with the number 001 needs to be updated in real time. After the data processor completes the update operation on the distributed transaction data with the number 001, the current target local transaction number is updated to be 002, that is, the distributed transaction data with the number 002 needs to be updated in real time. The transaction processing sequence is also the time sequence for processing each local transaction number.

Specifically, when the data processing server polls the target queue for the first time, since the default value of the tag data of the data tag of the cache queue is the first tag data, and at this time, the data processing server may poll the message queue to obtain the distributed transaction data of the current target local transaction number, that is, the distributed transaction data of the first local transaction number, from the message queue according to the transaction sequence. In the subsequent data processing process, if the tag data of the buffer queue data tag of the buffer queue is the second tag data, and at this time, the buffer queue has buffer data, the data processing server may poll the message queue and the buffer queue, so as to obtain the distributed transaction data of the current target local transaction number from the message queue or the buffer queue according to the transaction processing sequence.

Correspondingly, in the process of polling the message queue, if the data currently acquired by the data processing server from the message queue is not the distributed transaction processing data of the current target local transaction number, the data processing server may cache the currently acquired data in the cache queue. At this time, if the flag data of the buffer queue data flag is the first flag data, it needs to be set as the second flag data. If the data currently acquired by the data processing server from the message queue is the distributed transaction data of the current target local transaction number, the data processing server may continue to poll the target queue, or synchronously update the acquired distributed transaction data of the current target local transaction number to the database.

S120, synchronously updating the distributed transaction processing data acquired in sequence to an aggregation database according to the transaction processing sequence.

Optionally, the sequentially acquired distributed transaction data is synchronously updated to the aggregation database according to the transaction sequence, where each time one distributed transaction data is sequentially acquired, that is, the distributed transaction data is synchronously updated to the aggregation database; or after all distributed transaction data corresponding to the real-time data update operation are acquired according to the transaction processing sequence, all distributed transaction data are synchronously updated to the aggregation database according to the transaction processing sequence, as long as the aggregation database can be updated according to the time sequence of the distributed transaction data, and the embodiment of the invention does not limit the update mode of the distributed transaction data.

In an optional embodiment of the present invention, after synchronously updating the sequentially acquired distributed transaction data to the aggregation database according to the transaction order, the method may further include: resetting the flag data of the buffer queue data flag to the first flag data.

In a specific example, the data processing server obtains the local transaction numbers LT001, LT002 and LT003 corresponding to the global transaction number GT001 from the global transaction processor, and LT001, LT002 and LT003 may form a group of transaction number groups. Further, the data processing server polls the distributed transaction processing data corresponding to the local transaction numbers from the message queue and/or the cache queue, and aggregates the polled distributed transaction processing data into the aggregation database.

Step one, the data processing server polls the message queue, and if the data processing server acquires the first local transaction number in the sequence of the transaction number groups LT001, LT002 and LT003, namely the distributed transaction processing data corresponding to LT001, the first local transaction number is synchronously updated to the aggregated data. If the transaction data is not the distributed transaction data corresponding to the LT001, the data processing server stores the transaction data into the cache queue, and sets a cache queue data flag associated with the global transaction number GT001 as true in the cache queue. Or, the data processing server may also cache the acquired distributed transaction data corresponding to LT001, for example, cache the distributed transaction data to the local, and wait to acquire distributed transaction data of other local transaction numbers in sequence.

And secondly, if the data processing server completes processing of the distributed transaction data corresponding to the LT001 and the data processing server detects that the cache queue data mark associated with the global transaction number GT001 in the cache queue is true, polling data from the message queue and the cache queue respectively. And if the data processing server acquires the distributed transaction processing data corresponding to the second local transaction number, namely LT002, in the sequence of the transaction number groups LT001, LT002 and LT003, synchronously updating the distributed transaction processing data to the aggregated data. If the transaction data is not the distributed transaction data corresponding to the LT002, the data processing server saves the transaction data into the cache queue. At this time, if the cache queue data flag associated with the global transaction number GT001 is set as true in the cache queue, the cache queue data flag does not need to be modified, and if the cache queue data flag associated with the global transaction number GT001 is set as false in the cache queue, the cache queue data flag associated with the global transaction number GT001 needs to be set as true. If the data processing server completes processing of the distributed transaction processing data corresponding to the LT001 and the data processing server detects that the cache queue data flag associated with the global transaction number GT001 in the cache queue is false, continuing polling data from the message queue to acquire the distributed transaction processing data corresponding to the LT 002. Or, the data processing server may also cache the acquired distributed transaction data corresponding to LT002 in the distributed transaction data location corresponding to LT001, and wait to sequentially acquire distributed transaction data of other local transaction numbers.

And step three, if the data processing server completes processing of distributed transaction processing data corresponding to LT001 and LT002 and the data processing server detects that a cache queue data mark associated with the global transaction number GT001 in the cache queue is true, polling data from the message queue and the cache queue respectively to obtain the distributed transaction processing data corresponding to LT003. If the data processing server completes processing of distributed transaction processing data corresponding to LT001 and LT002 and the data processing server detects that the cache queue data flag associated with the global transaction number GT001 in the cache queue is false, the data processing server continues polling data from the message queue to acquire distributed transaction processing data corresponding to LT003. After the data processing server acquires the distributed transaction data corresponding to LT003, it may synchronously update the distributed transaction data to the aggregated data. Or, the data processing server may cache the acquired distributed transaction data corresponding to LT003 in the distributed transaction data location corresponding to LT 002. At this time, the data cached by the data processing server in the time sequence of the local transaction number is distributed transaction data corresponding to LT001, LT002, and LT003, respectively. The data processing server can synchronously update distributed transaction data corresponding to LT001, LT002 and LT003 to the aggregation database according to the sequence of LT001-LT002-LT 003.

After the data processing server completes the update operation of the distributed transaction processing data corresponding to all the local transaction numbers LT001, LT002, and LT003 in the transaction number group corresponding to the global transaction number GT001, the cache queue data flag associated with the global transaction number in the cache queue may be reset to false.

Therefore, the distributed transaction processing data in the application data table in the distributed database are sequentially aggregated to the aggregated database used for specific query, so that the time sequence of real-time data updating in the aggregated database can be ensured, and the accuracy and reliability of real-time data updating in the aggregated database are improved.

Example two

Fig. 2 is a flowchart of a real-time data updating method according to a second embodiment of the present invention, where this embodiment is applicable to a case where distributed transaction data that needs to be updated in real time is generated by a local transaction processor, so as to further update the real-time data synchronously according to a chronological order through a data processing server, a message queue, and a cache queue, and the method may be executed by a real-time data updating apparatus configured in the local transaction processor, where the apparatus may be implemented by software and/or hardware, and may be generally integrated in an electronic device, where the electronic device may be a terminal device or a server device, and is used in cooperation with a global transaction processor and a data processing server. Accordingly, as shown in fig. 2, the method includes the following operations:

and S210, acquiring a local transaction number issued by the global transaction processor according to the real-time data updating operation.

The local transaction processor can be used as a transaction initiator and is responsible for starting, submitting or rolling back distributed transactions, and can establish communication connection with the global transaction processor for interaction. The global transaction processor can be used as a transaction coordinator and is responsible for promoting the distributed transaction and managing the life cycle of the transaction. Alternatively, the global transaction processor may be a processor running in a centralized database.

And S220, executing the distributed transaction according to the local transaction number to obtain distributed transaction processing data.

In the embodiment of the present invention, the global transaction processor may generate a global transaction number corresponding to the real-time data update operation and each local transaction number under the global transaction number. After the global transaction processor generates the local transaction number, the local transaction number can be issued to the local transaction processor, and the local transaction processor processes each distributed transaction of the real-time data updating operation according to the local transaction number to generate distributed transaction processing data. Optionally, there may be one or multiple local transaction processors for processing the distributed transaction corresponding to each local transaction number, which is not limited in this embodiment of the present invention.

S230, pushing the distributed transaction processing data to a message queue for storage.

Correspondingly, after the local transaction processor obtains the distributed transaction processing data, the distributed transaction processing data can be pushed to a message queue for storage so as to be consumed by the data processing server. The data processing server may poll the message queue, and cache the distributed transaction data of the current local transaction number in the cache queue when it is determined that the acquired distributed transaction data of the current local transaction number is not the distributed transaction data of the current target local transaction number. In the subsequent process, the data processing server may poll the message queue and/or the cache queue according to the cache queue data flag, sequentially obtain the distributed transaction data of each local transaction number under the global transaction number corresponding to the real-time data updating operation, and synchronously update the sequentially obtained distributed transaction data to the aggregation database according to the transaction sequence.

According to the embodiment of the invention, the local transaction number issued by the global transaction processor according to the real-time data updating operation is acquired through the local transaction processor, the distributed transaction is executed according to the local transaction number, the distributed transaction data is obtained, and the distributed transaction data is pushed to the message queue for storage, so that the distributed transaction data is synchronously updated to the aggregation server by the data processing server according to the transaction sequence, the problem that the time sequence of real-time data updating cannot be ensured in the existing real-time data updating method is solved, the time sequence of real-time data updating can be ensured, and the accuracy and reliability of real-time data updating are improved.

EXAMPLE III

Fig. 3 is a flowchart of a real-time data updating method according to a third embodiment of the present invention, where this embodiment is applicable to a situation where a global transaction processor generates a transaction number and sends the transaction number to a local transaction processor and a data processing server, so that the local transaction processor further generates distributed transaction data that needs to be updated in real time, and the distributed transaction data is synchronously updated according to a time sequence through the data processing server, a message queue and a cache queue. Accordingly, as shown in fig. 3, the method includes the following operations:

s310, responding to the real-time data updating operation, and generating a global transaction number and a local transaction number corresponding to the real-time data updating operation.

In the embodiment of the present invention, after the user executes the service operation through the system front end of the real-time data updating system, the global transaction processor in the real-time data updating system may generate the global transaction number and the local transaction number corresponding to the real-time data updating operation in response to the real-time data updating operation.

And S320, sending the global transaction number and the local transaction number corresponding to the real-time data updating operation to a data processing server.

S330, receiving the transaction number related information fed back by the data processing server, and pushing the local transaction number to a local transaction processor under the condition that the transaction number related information is verified, so that the local transaction processor executes a distributed transaction according to the local transaction number to obtain distributed transaction processing data.

And the distributed transaction processing data is used for synchronously updating the data processing server to the aggregation server according to the transaction processing sequence. The transaction number related information may be information related to the transaction number, for example, the transaction number itself, or character information generated by the transaction number, and the like.

Further, the global transaction processor may send the generated global transaction number and the local transaction number to the data processing server for verification. After receiving the global transaction number and the local transaction number, the data processing server may feed back the transaction number association information to the global transaction processor, for example, directly feed back the received global transaction number and the local transaction number, or encrypt the global transaction number and the local transaction number by using an encryption algorithm to generate an encrypted character string, which is fed back to the global transaction processor as the transaction number association information. And after receiving the transaction number association information fed back by the data processing server, the global transaction processor verifies the transaction number association information. For example, if the transaction number association information is a global transaction number and a local transaction number, it may be directly checked whether the global transaction number and the local transaction number are the same as the transaction number information issued to the data processing server. If the transaction number association information is an encrypted character string generated by encrypting the global transaction number and the local transaction number by using an encryption algorithm, the encrypted character string can be decrypted to obtain the global transaction number and the local transaction number, and whether the global transaction number and the local transaction number are the same as the transaction number information issued to the data processing server or not is verified. The global transaction processor may push the local transaction number to the local transaction processor if it is determined that the transaction number association information passes the check. And the local transaction processor executes the distributed transaction according to the received local transaction number to obtain distributed transaction processing data. The data processing server may poll the target queue according to the received global transaction number and the received local transaction number, determine whether the distributed transaction data of the current local transaction number is the distributed transaction data of the current target local transaction number, and sequentially obtain the distributed transaction data of each local transaction number under the global transaction number corresponding to the real-time data updating operation.

The embodiment of the invention responds to the real-time data updating operation through the global transaction processor, generates the global transaction number and the local transaction number corresponding to the real-time data updating operation, sends the global transaction number and the local transaction number to the data processing server, and receives the transaction number association information fed back by the data processing server. And under the condition that the transaction number association information is verified, pushing the local transaction number to a local transaction processor, so that the local transaction processor executes the distributed transaction according to the local transaction number to obtain distributed transaction processing data. Further, the data processing server polls the message queue and/or the cache queue according to the cache queue data mark to sequentially acquire the distributed transaction data of each local transaction number under the global transaction number corresponding to the real-time data updating operation, so that the sequentially acquired distributed transaction data is synchronously updated to the aggregated database according to the transaction processing sequence, the problem that the existing real-time data updating method cannot guarantee the time sequence of real-time data updating is solved, the time sequence of real-time data updating can be guaranteed, and the accuracy and the reliability of real-time data updating are improved.

Example four

Fig. 4 is a flowchart of a real-time data updating method according to a fourth embodiment of the present invention, and as shown in fig. 4, the method includes the following operations:

s410, responding to a real-time data updating operation through a global transaction processor, and generating a global transaction number and a local transaction number corresponding to the real-time data updating operation.

Optionally, the data processing server is specifically configured to: polling the message queue to obtain distributed transaction processing data of the current target local transaction number according to the transaction processing sequence under the condition that the mark data of the data mark of the cache queue is determined to be first mark data; polling the message queue and the cache queue to obtain distributed transaction processing data of the current target local transaction number according to the transaction processing sequence under the condition that the mark data of the cache queue data mark is determined to be second mark data; and when the distributed transaction processing data of the current local transaction number acquired by polling the target queue is not the distributed transaction processing data of the current target local transaction number, the distributed transaction processing data of the current local transaction number is used for caching into the cache queue.

Optionally, the data processing server is further configured to: and resetting the mark data of the data mark of the cache queue to the first mark data after synchronously updating the distributed transaction processing data acquired in sequence to an aggregation database according to the transaction processing sequence.

In a specific example, the real-time data updating method may specifically include the following operations:

step one, prepositive preparation work:

step 1.1, each time a user executes a real-time data updating operation through the system front end of the real-time data updating system, the global transaction server generates a global transaction number such as GT001 for the real-time data updating operation, and generates a group of sequential local transaction numbers LT001, LT002 and LT003 corresponding to the global transaction number GT 001. Alternatively, a set of local transaction numbers may be collectively referred to as a transaction number set. The order of the local transaction numbers in the transaction number group represents the local transaction commit order intended by the global transaction server when committing the global transaction.

Step 1.2, the global transaction processor establishes communication connection with the data processing server, and sends the global transaction number GT001 corresponding to the business operation and the included local transaction numbers LT001, LT002 and LT003 to the data processing server. And the data processing server confirms the receipt after receiving the transaction number and returns the transaction number association information to the global transaction processor. Meanwhile, the data processing server may locally store the received transaction number.

And step 1.3, the global transaction processor receives the transaction number association information returned by the data processing server, checks the transaction number association information and sends the group of local transaction numbers to the local transaction processor after confirming no errors.

And step two, the local transaction processor performs distributed transaction according to the local transaction numbers LT001, LT002 and LT003, and submits the content to the message queue after completion.

Step 2.1, the local transaction handler performs the opening, committing and rollback of the distributed transaction according to local transaction numbers LT001, LT002 and LT003. The local transaction number LT001 may correspond to an opened distributed transaction, the local transaction number LT002 may correspond to a submitted distributed transaction, and the local transaction number LT003 may correspond to a rolled-back distributed transaction.

And 2.2, after the local transaction processor finishes processing the distributed transaction, pushing the obtained distributed transaction processing data to a message queue. It will be appreciated that the distributed transaction data stored in the message queue may be out of order or stored sequentially due to various factors such as network quality.

And step three, the data processing server polls data from the message queue and the cache queue according to the global transaction number GT001 and the corresponding transaction number groups LT001, LT002 and LT003 acquired from the global transaction processor, and synchronously updates the data to the aggregation server according to the transaction processing sequence.

And 3.1, polling the message queue by the data processing server, and if the distributed transaction processing data of the current target local transaction number in the transaction number group LT001, LT002 and LT003 sequence, such as the distributed transaction processing data of LT001, synchronously updating the distributed transaction processing data to the aggregation server. If the distributed transaction data is not the distributed transaction data of the current target local transaction number, the distributed transaction data is stored in the cache queue, and the flag bit associated with the global transaction number GT001 of the cache queue is set to true.

And 3.2, in the process of polling data in the later period, if the flag bit associated with the global transaction number GT001 in the cache queue is true, the data processing server polls the data from the message queue and the cache queue respectively. If the distributed transaction data of the current target local transaction number in the sequence of the transaction number groups LT001, LT002 and LT003, such as LT002, is acquired, the distributed transaction data is synchronously updated to the aggregation server. If the flag bit associated with the global transaction number in the buffer queue is false, the operation of step 3.1 is performed.

And 3.3, after the data processing server completes the synchronous updating operation of the distributed transaction processing data of all the local transaction numbers LT001, LT002 and LT003 in the transaction number group corresponding to the global transaction number GT001, setting the flag bit associated with the global transaction number in the cache queue as false, and disconnecting the communication connection with the global transaction processor.

It should be noted that, after polling the distributed transaction data of the current target local transaction number, the data processing server may temporarily not update the distributed transaction data to the aggregation server in synchronization, but cache the distributed transaction data locally. After the data processing server caches the distributed transaction processing data of all local transaction numbers in sequence, statistics can be carried out on the cached distributed transaction processing data, and the cached distributed transaction processing data can be synchronously updated to the aggregation database according to the transaction processing sequence.

Compared with the existing real-time data updating method, the real-time data updating method can effectively solve the problem of orderliness in the data aggregation process, and further ensure the orderliness of querying database data after aggregation. By the real-time data aggregation method for keeping the orderliness, the problem that data query and actual service operation results are different after data aggregation is carried out on fragment database data can be solved.

The embodiment of the invention responds to the real-time data updating operation through the global transaction processor, generates the global transaction number and the local transaction number corresponding to the real-time data updating operation, sends the global transaction number and the local transaction number to the data processing server, and receives the transaction number association information fed back by the data processing server. And under the condition that the transaction number association information is verified, pushing the local transaction number to a local transaction processor, so that the local transaction processor executes the distributed transaction according to the local transaction number to obtain distributed transaction processing data. Further, the data processing server polls the message queue and/or the cache queue according to the cache queue data mark, and sequentially obtains the distributed transaction data of each local transaction number under the global transaction number corresponding to the real-time data updating operation, so that the sequentially obtained distributed transaction data are synchronously updated to the aggregated database according to the transaction sequence, the problem that the existing real-time data updating method cannot guarantee the time sequence of real-time data updating is solved, the time sequence of real-time data updating can be guaranteed, and the accuracy and reliability of real-time data updating are improved.
