Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
First, the terms referred to in the embodiments of the present application will be briefly described:
1)Redis
redis is a new memory caching technology, is a storage system based on key-value structure data, and has the characteristics of high performance reading and writing, multi-data type support, data persistence, high available architecture, user-defined virtual memory support, distributed fragment clustering support, extremely high single-thread reading and writing performance and the like; the data structure storage system in the memory can be used as a database, a cache and message middleware. The data storage system is basically matched with a back-end database to store data which are frequently called by a user at present.
Redis is atomicity, i.e., an operation is not subdividable, either executed or not executed.
2)Tair
Tair is a storage system of key-value structure data, supports two storage modes based on memory and files by default, and corresponds to cache and persistent storage respectively. Tair functions are get, put, delete, and bulk interface.
3) Message Queue (MQ)
A message queue is a method of communication from an application to an application. Applications communicate by writing and retrieving queued data (messages) for the application without requiring a dedicated connection to link them. Message passing refers to the communication between programs by sending data in a message, rather than communicating with each other through direct calls, which are often used for techniques such as remote procedure calls. Queuing refers to the application communicating through a queue. The use of a message queue removes the requirement that the receiving and sending applications execute simultaneously.
4) Delaying messages
The delayed message means that the producer cannot be consumed by the consumer immediately after sending the message, and the producer can wait for a specified time before being consumed.
There are two delay strategies available for accessing MQ delayed messages, consuming group granularity delay and message granularity delay. The delay time supported by the message granularity delay is controlled at the production end and is limited by the delay time (5s-30 days), and the delay time of the consumption group granularity is controlled by the consumption end and is not limited. In the present embodiment, a consumption group granularity delay is employed.
Referring to fig. 1, which shows a schematic diagram of a content data updating system according to an exemplary embodiment of the present application, as shown in fig. 1, the content data updating system 100 includes a merger 101, a timer 102, and an executor 103.
The combiner 101 adopts a main standby mode, taking Redis as a main mode and Tair as an auxiliary mode; in the operation process of the content data updating system, if the Redis has a problem, the system can be switched to Tair in time to maintain the normal operation of the content data updating system. In the merger, change information of the same piece of content data is aggregated to the same key through key bizId _ bizType to achieve deduplication of the change information of the same piece of content data, wherein bizId represents an ID of the content data, bizType represents a type of the content data, and value is a timestamp used for recording a time when the change information of the same piece of content data is received for the first time.
The timer 102 adopts a design scheme based on Mafka delay messages, adds delay messages for different content data sent in the merger into a Mafka delay queue, and waits to be consumed by an executor.
The executor 103 is configured to listen to the delay message in the Mafka delay queue, and after receiving the delay message in the Mafka delay queue, execute a corresponding operation in response to the delay message.
Referring to fig. 2, which shows a flowchart of a content data updating method shown in an exemplary embodiment of the present application, the method may be performed by a content data updating system, which may be the content data updating system of fig. 1, and as shown in fig. 2, the method may include the following steps:
In a possible implementation manner, when content data is updated, after the content data of the content data production end is updated, content data change information needs to be submitted to a content data updating system, and the content data updating system instructs the consumption end to update and synchronize the content data by starting a content data importing process.
In one possible implementation manner, the information identifier of the change information includes an ID of the content data and a type of the content data, and the ID (Identity Document) of the content data and the type of the content data indicate unique content data, and the type of the content data includes: note, short video, rating, etc. Each piece of content data contains at least one piece of sub-data, which is represented by associating each piece of content data with a plurality of basic elements, the basic elements include at least one of characters, pictures and videos, for example, a note can be associated with hundreds of pictures and a plurality of pieces of character content data, and when the content data is updated, a piece of change information is generated by changing each basic element in the same content data, and the change information indicates that the content data has changed.
In a possible implementation manner, an information identifier set is provided in the content data updating system, and is used for storing information identifiers of change information for different content data, where the information identifiers stored in the information identifier set are non-repetitive, that is, only one change information exists in the information identifier set for the same content data at the same time. When the target information identifier is different from the information identifier in the information identifier set, it is indicated that the target change information is the first change information of the corresponding content data, and the target information identifier is added into the information identifier set to deduplicate other change information received within a specified time.
In response to receiving the changed information having the same information identifier as the target information identifier within the specified time period, the changed information is not processed, step 230.
In a possible implementation manner, the content data updating system starts to time after receiving the first change information for the corresponding content data until reaching a specified time length. When the change information with the same information identifier as the target information identifier is received in the specified time length, the content data corresponding to the change information and the target change information are determined to be the same, and the update of the same content data is indicated.
And 240, responding to the end of the specified duration, and updating the content data of the consuming terminal according to the target information identification.
In a possible implementation manner, in response to the end of the specified duration, the content data updating system starts a content data importing process, and updates and synchronizes the content data according to the target information identifier update consuming end.
To sum up, in the content data updating method provided in the embodiment of the present application, repeated change information indicating that the same content data of a production end has been changed is merged into a piece of target change information within a specified duration range, and after the specified duration is over, the corresponding content data of a consumption end is updated according to the target change information, so that in the content data updating process, the importing process of the content data is only executed once for the same content data within the specified duration range, thereby avoiding the operation of starting the importing process of the same content data for multiple times within a short time, reducing the pressure on a service layer, and reducing the waste of thread resources and machine resources.
Referring to fig. 3, which shows a flowchart of a content data updating method shown in an exemplary embodiment of the present application, the method may be performed by a content data updating system, which may be the content data updating system of fig. 1, and as shown in fig. 3, the method may include the following steps:
In a possible implementation manner, the target change information is generated after any basic element in the corresponding content data is updated, where the updating of the basic element includes modification of the basic element, increase of the basic element, decrease of the basic element, and the like, for example, in a note containing ten pictures, one of the pictures is replaced, or one of the pictures is deleted, or one of the pictures is added, which all belong to updating of the basic element, and each updating of the basic element generates one piece of change information for the content data, and the target change information is any one of the pieces of change information.
In one possible implementation manner, the target information identifier of the target change information is expressed as: key-bizID _ bizType.
In a possible implementation manner, the target change information is generated after any sub-data integrity audit in the content data passes. When the content data of the production end is updated, each sub-data in the content data is sent to integrity audit, after the integrity audit is finished, each sub-data responds to a corresponding integrity audit result to indicate that the corresponding sub-data is legal, and each sub-data correspondingly generates a piece of change information to indicate that the content data corresponding to the sub-data is updated.
And 320, responding to the target information identifier different from the information identifiers in the information identifier set, adding the target information identifier to the information identifier set, and simultaneously generating a delay message related to the target change information, wherein the information identifiers in the information identifier set are non-repetitive, and the delay message comprises the target information identifier and a target interface corresponding to the target change information.
In a possible implementation manner, when it is determined that the target change information is change information that is sent for the first time with respect to a certain content data, the content data update system adds a target information identifier corresponding to the target change information to an information identifier set, and adds a delay message related to the target change information to a delay queue after a specified time length is finished according to the delay message, so as to instruct the update of the content data of the consuming end according to the delay message.
In a possible implementation manner, the delay message includes a target information identifier and a target interface corresponding to the target change information. The target information identifier is used for determining the ID and the type of content data updated by the production end through the target information identifier when indicating that content data of the consumption end is updated, the target interface corresponding to the target change information is used for indicating that a call of a corresponding target interface is triggered to update corresponding content data, a mapping relation exists between the target interface and the type of the content data, that is, which target interface is triggered is determined according to the type of the content data in the target information identifier, for example, bizType indicates that the type of the content data corresponding to the change information is a note, and the target interface is an import interface of the note content data; the bizType indicates that the type of the content data corresponding to the change information is short video, and the target interface is an import interface of the short video content data.
In one possible implementation manner, in response to that the target information identifier is different from the information identifiers in the information identifier set, a timestamp corresponding to the target change information is added to the timestamp set.
In one possible implementation, each piece of change information is associated with a unique timestamp to record the time when the change information is received by the content data update system. When the target change information is determined to be the change information which is transmitted for the first time aiming at a certain content data, the timestamp corresponding to the target change information is added to the timestamp set, that is, a plurality of pieces of change information aiming at the same content data can be provided within a period of time, the timestamp of each piece of change information is unique, only the timestamp set is recorded within the period of time, the timestamp of the first piece of change information aiming at the same content data is ignored, so that the content data updating system senses the time when the content data is updated for the first time within the period of time, and the timestamp corresponding to the target change information is recorded in the form of value.
In one possible implementation, the timestamp is recorded as a 13-bit millisecond timestamp, such as: 1592295928578, the time for receiving the change information is 2020-06-1616: 25:28:578, so as to ensure the uniqueness of the time stamp corresponding to each change information.
In a possible implementation manner, the specified time length is counted when it is determined that the target information identifier of the target change information is different from the information identifiers in the information identifier set, and since timestamps of receiving the first piece of change information corresponding to different content data are overlapped or have a difference, the starting points of the specified time lengths corresponding to different content data may be the same or different. That is, at the same time, the content data update system may receive a plurality of pieces of change information, which are pieces of change information for different pieces of content data, for example, when the time stamp is 1592295928578, 3 pieces of change information are received at the same time, and the 3 pieces of change information are different from each other and are pieces of change information for 3 pieces of different content data, where change information 1 is the first piece of change information for content data 1, and therefore, when change information 1 is received, the specified duration timer for change information 1 is started; if the change information 2 is the non-first piece of change information for the content data 2, the change information 2 is not processed, and the corresponding designated time length counter is not triggered; since the change information 3 is the first piece of change information for the content data 3, the specified time period for the change information 3 is started when the change information 3 is received.
In a possible implementation manner, after the specified duration is over, the updated update data in the content data is back-checked in response to the target change information according to the target information identifier and the target interface included in the delay information.
In one possible implementation, the target interface is called using an RPC (Remote Procedure Call Protocol) generalized Call principle.
The RPC generalized call refers to that a Service call end directly initiates a Service call through a Generic Service interface under the condition that an interface jar packet does not need to be introduced. All POJOs in the parameters and return values are represented by maps. The generalized call does not need to pay attention to the service provider, and the exposure can be performed according to the normal service.
In the embodiment of the application, since different types of content data need to trigger different import interfaces of the content data, if jar packets need to be reintroduced every time a content type is newly accessed, the extensibility is poor due to the encapsulation of the call logic of the interfaces. The call to the target interface is thus realized by a generalized call.
And step 350, updating the content data in the consuming side according to the updating data.
In one possible implementation, updating the content data in the consuming side according to the update data includes: the method comprises the steps of converting and packaging updated data, preprocessing before warehousing (sensitive word filtering, picture structuring and the like), warehousing the data and post-processing the data (watermark detection, portrait detection and the like).
In one possible implementation manner, in response to failure of the operation of updating the content data in the consuming side according to the update data, a delay message of execution failure is added into the retry queue, and the number of execution failures of the delay message is recorded.
In one possible implementation manner, to avoid the influence of backlog of retry messages in the retry queue on normal execution of the delay messages in the delay queue, the retry queue is isolated from the delay queue, and the delay message that fails to be executed is retried in the retry queue until the execution succeeds or the number of execution failures exceeds a threshold number of failure times, please refer to fig. 4, which shows a schematic diagram of a retry procedure shown in an exemplary embodiment of the present application, and as shown in fig. 4, the retry procedure includes the following steps:
s410, a retry queue is listened.
And S420, responding to the monitored retry message in the retry queue, and acquiring the execution failure times of the retry message.
The retry message is a delay message of execution failure in the delay queue.
S430, responding to the execution failure times of the retry message being larger than the failure time threshold, reporting the retry message by dotting, and triggering an alarm.
And S440, reading the retry message in response to the execution failure times of the retry message not being more than the failure time threshold value.
The retry message includes an information identifier corresponding to the change information and an interface corresponding to the change information.
S450, updating the content data of the consuming end according to the retry message.
S460, determining whether the retry message is successfully executed, if so, ending the process, otherwise, executing step S470.
S470, record the number of failures of the retry message, and add the retry message to the retry queue again.
And step 360, deleting the target information identifier in the information identifier set.
In one possible implementation manner, to implement deduplication of the change information based on the specified duration, the target information identifier in the information identifier set is deleted after the specified duration is ended.
Because the time length of the specified duration is fixed, in a possible case, within the first specified duration, the change information for the same piece of content data is not received completely, and there is still change information for the content data subsequently, if the information identifier of the content data is always stored in the information identifier set, the change information for the content data subsequently is judged to be repeated change information and is not processed, but for the content data at the consuming end, the synchronization progress is only synchronized to the state at the end of the first specified duration, the change information for the content data subsequently cannot start the import program, so that data inconsistency occurs, for example, the specified duration is 1s, 5 pieces of change information for the content data a within the 1s are left after deduplication and merging, and corresponding delay messages are generated, after the specified duration is over, the delay message corresponding to the change information is consumed, if the immediate confirmation mechanism after consumption is not set, the subsequent change information aiming at the content data A is de-overlapped, but the corresponding delay message is not generated, so that the subsequent change information aiming at the content data A is not processed, and the update state of the content data A at the consumption end stays at the state of 1s end.
Or, in a possible case, there is a certain delay precision in the message queue delay message, under the action of the delay precision, the delay message will be consumed in advance, for example, the delay precision is 100ms, in a certain time window (assuming 1s), there are 5 pieces of change information of the content data a in the time period from 0ms to 900ms in the window, only 1 piece of change information is left after deduplication and combining, and a corresponding delay message is generated, and at the time of 900ms, the delay message is consumed in advance due to the delay precision problem, and one piece of change information of the content data a is received between 900ms and 1000 ms. If an instant confirmation mechanism after consumption is not designed, the last change information is lost, and the re-import of the content data A is not triggered, so that the last change of the content data A is not synchronized, and the data of the systems of the two parties are inconsistent.
Therefore, in order to avoid data inconsistency between the production end and the consumption end caused by the two situations, an instant confirmation mechanism after consumption is added, namely, when the target change information is responded, the target information identifier in the information identifier set is deleted. When the next change information which is the same as the content data corresponding to the target change information is received, the corresponding delay message can be regenerated, and the content data of the consuming end can be updated.
In a possible implementation manner, after the content data of the consuming end is identified according to the target information, the timestamp corresponding to the target change information in the timestamp set is deleted, so that when next change information for the same content data comes, and when the first change information of the content data in a new specified time length of the change information comes, the change information in the time length is deduplicated and a corresponding delay message is generated.
In response to the target information identity being the same as any of the set of information identities, the target change information is not processed, step 370.
In a possible implementation manner, in order to avoid a situation that, due to accidental factors, after content data of a consuming end is updated according to an information identifier, a corresponding information identifier in an information identifier set is not deleted, so that subsequent change information cannot be responded, the application provides a polling method:
querying the set of timestamps at a specified period;
responding to an abnormal time stamp which is more than a time threshold value from the current query time in the time stamp set, and responding to the change information corresponding to the abnormal time stamp again;
and deleting the information identifier of the target change information corresponding to the abnormal timestamp from the information identifier set.
It should be noted that, in the embodiment of the present application, the change information indicates that the content data corresponding to the production end has changed, so as to notify the content data updating system to synchronously update the content data of the consumption end, during this process, the update of each basic element of the content data sends a piece of change information to the content data updating system, but indicates that the content data has changed. In the embodiment of the present application, the change information for the same content data received in the specified time period is merged, that is, each original basic element is changed, and the content data is updated once in response to one change information, which is optimized to merge the change information for the same content data occurring in the specified time period into one piece, and to update the content data synchronously after the specified time period is timed out. Therefore, the content data updating method disclosed by the application is applied to scenes with low real-time requirements on content data updating.
To sum up, in the content data updating method provided in the embodiment of the present application, repeated change information indicating that the same content data of a production end has been changed is merged into a piece of target change information within a specified duration range, and after the specified duration is over, the corresponding content data of a consumption end is updated according to the target change information, so that in the content data updating process, the importing process of the content data is only executed once for the same content data within the specified duration range, thereby avoiding the operation of starting the importing process of the same content data for multiple times within a short time, reducing the pressure on a service layer, and reducing the waste of thread resources and machine resources.
In one possible implementation, the content data updating system is composed of a merger, a timer and an executor, and may be the content data updating system shown in fig. 1.
The merger is used for responding to the received target change information and acquiring a target information identifier of the target change information; adding the target information identifier to the information identifier set in response to the target information identifier being distinct from the information identifiers in the information identifier set; in response to receiving the change information with the information identifier being the same as the target information identifier within the specified time period, not processing the change information; the target information identifier is used for identifying content data corresponding to the target change information; the target change information is generated corresponding to any subdata in the content data when the content data of the production end is updated; the target change information is used for triggering the update of the content data of the consuming terminal.
The timer is used for setting a specified duration; responding to the end of the specified duration, and sending a delay message generated according to the target change information to an actuator;
the executor is used for updating the content data of the consuming end according to the delay message.
Referring to fig. 5, which shows a flowchart of a content data updating method according to an exemplary embodiment of the present application, the method is interactively performed by a merger, a timer and an executor, and as shown in fig. 5, the content data updating method includes:
in step 501, the merger acquires the target information identifier of the target change information in response to receiving the target change information.
Step 502, the merger determines whether the target information identifier exists in the information identifier set, if so, the merger does not respond to the target change information, otherwise, step 503 is executed.
In step 503, the merger adds the target information identifier to the information identifier set.
In step 504, the combiner generates delay information corresponding to the target change information.
Step 505, the combiner sends the delay information to the timer, and correspondingly, the timer receives the delay information.
In step 506, the timer starts a specified duration for timing.
In step 507, the timer responds to the end of the timing of the specified duration, and adds the delay information to the delay queue for consumption by the actuator.
In step 508, the executor responds to the monitored delay information in the delay queue to read the delay information.
In step 509, the executor updates the content data of the consuming end according to the delay information.
Step 510, the executor performs consumption instant feedback to the merger, and instructs the merger to delete the target information identifier in the information identifier set.
To sum up, in the content data updating method provided in the embodiment of the present application, repeated change information indicating that the same content data of a production end has been changed is merged into a piece of target change information within a specified duration range, and after the specified duration is over, the corresponding content data of a consumption end is updated according to the target change information, so that in the content data updating process, the importing process of the content data is only executed once for the same content data within the specified duration range, thereby avoiding the operation of starting the importing process of the same content data for multiple times within a short time, reducing the pressure on a service layer, and reducing the waste of thread resources and machine resources.
