The present invention relates to the field of data processing technologies, and in particular, to a method, an apparatus, a device, and a storage medium for generating a business global serial number.

Background

In the distributed system, when one customer service request is completed by a plurality of background systems together, the service request adopts a global serial number for unique identification, which is the unique transaction association generated in the processing process of the customer service request, and the initial initiator system circulates in the whole transaction process. The execution of a service request spans a plurality of system modules, the result of the service execution is also dispersed in a plurality of systems, and the global serial number is a correlation mechanism for cross-system transaction, and can trace the service and monitor and ensure the data consistency of each system.

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 other sequences than those illustrated or described herein.

Example one

Fig. 1 is a flowchart of a method for generating a global serial number of a service according to an embodiment of the present invention, where this embodiment is applicable to a case of generating a global serial number of a service, and the method may be executed by a device for generating a global serial number of a service, and the device may be implemented in a form of hardware and/or software. As shown in fig. 1, the method includes:

step S101, acquiring attribute information of transaction service.

Optionally, before obtaining the attribute information of the transaction service, the method further includes: acquiring serial numbers in a specified range from a database; and respectively caching the serial numbers in the specified range into a first-level cache unit and a second-level cache unit, wherein the range of the serial numbers in the first-level cache unit is different from that in the second-level cache unit.

In this embodiment, in order to alleviate an excessive dependency of a global serial number generation process on a database, sequence numbers stored in the database are firstly cached in a first-level cache unit and a second-level cache unit before a transaction service is acquired, because storage spaces corresponding to the first-level cache unit and the second-level cache unit are fixed, only sequence numbers in a specified range stored in the database are respectively cached in the cache units, ranges of the sequence numbers in the first-level cache unit and the second-level cache unit are different, and a length of each sequence number in the cache unit may specifically be 16 bits.

It should be noted that, in this embodiment, each cache unit respectively adopts a self-increment mode to display the serial number, for example, for a first-level cache unit, the initial display serial number 0000000000000001 sets a self-increment step size to 1, that is, 1 is added when it is determined that the serial number 0000000000000001 is removed, and a next serial number 0000000000000002 is displayed until a maximum value 0000000000000010 of the cached serial number is removed, and then the first cache unit is empty. Of course, in this embodiment, only the first-level cache unit is taken as an example for description, and the display manner of the serial numbers of the second-level cache unit is substantially the same as this, which is not described in detail in this embodiment again.

Optionally, the obtaining attribute information of the transaction service includes: identifying the transaction service received by the service receiving unit to obtain a service type; determining the transaction time of the transaction service received by the service receiving unit and the receiving end identification corresponding to the service receiving unit; and taking the service type, the transaction time and the receiving end identification as attribute information.

Specifically, in this embodiment, when the transaction service is received by the service receiving unit, two pieces of information, namely, a receiving end identifier of the service receiving unit and transaction time for receiving the transaction service, are obtained, where the receiving end identifier may be 4 bits, and the transaction time may be 8 bits, which is only an example in this embodiment, and specific bits of the receiving end identifier and the transaction time are not limited. In addition, in this embodiment, the acquired transaction service is also identified to determine the service type, for example, the service type may be a deposit transaction or a withdrawal transaction, and in this embodiment, specific contents of the service type are not limited, and specifically, the transaction time, the service type, and the receiving end identifier are used as attribute information of the transaction service.

Step S102, obtaining the appointed serial number from the cache unit according to the business type of the transaction business.

Optionally, obtaining the specified sequence number from the cache unit according to the service type of the transaction service includes:

inquiring from a first-level cache unit according to the service type to acquire a serial number matched with the service type; and judging whether the serial number matched with the service type is valid, if so, taking the serial number matched with the service type as an appointed serial number, otherwise, updating the serial number of the first-level cache unit, and acquiring the appointed serial number according to the updated first-level cache unit.

Specifically, since serial numbers in different ranges are cached in the first-level cache unit and the second-level cache unit in advance, the serial number generator is used for querying from the first-level cache unit according to the acquired service type, and whether a serial number corresponding to the service type exists in the first-level cache unit is judged. For example, when the transaction service type is a withdrawal service, the serial number currently displayed in the primary cache unit is 0000000000000002, and each serial number corresponds to a different service type, so that it is determined whether the service type corresponding to the displayed serial number is a withdrawal service, if so, it is determined whether 0000000000000002 is valid, that is, whether the serial number is within a specified range of the database cache, and when the maximum cache serial number of the database for the primary cache unit is 0000000000000010, it may be determined that the currently displayed serial number is valid, and 0000000000000002 is directly used as the specified serial number.

When the currently displayed serial number is determined to be invalid, whether a serial number corresponding to the withdrawal service exists is further inquired from the primary cache unit, and when the maximum cache serial number 0000000000000010 is determined to be still not matched with the withdrawal service through traversal operation, the serial number in the primary cache unit is updated, so that the assigned serial number is obtained according to the updated primary cache unit.

Optionally, the updating the sequence number of the first-level cache unit includes: and judging whether the second-level cache unit contains the serial number, if so, directly writing the serial number in the second-level cache unit into the first-level cache unit to update the serial number of the first-level cache unit, otherwise, writing the serial number read from the database into the first-level cache unit and the second-level cache unit to update the serial number of the first-level cache unit and the second-level cache unit.

It should be noted that when it is determined that the sequence number that matches the transaction service and is valid is not found even after the first-level cache unit is traversed, the sequence number in the first-level cache unit is invalidated, whether the sequence number is included in the second-level cache unit is determined, and if the sequence number is included, the sequence number in the second-level cache unit is directly used to update the sequence number of the first-level cache unit. However, under the condition that the second-level cache unit does not contain the serial number, two segments of serial numbers are called from the database and cached in the first-level cache unit and the second-level cache unit respectively, and the caching priority of the first-level cache unit is higher than that of the second-level cache unit, namely, the serial numbers are cached in the second-level cache unit preferentially, so that the serial numbers can be ensured to exist in the first-level cache unit constantly, and effective serial numbers can be inquired from the first-level cache unit. Therefore, in this embodiment, the sequence number may be directly obtained from the first-level cache unit, or the sequence number may be obtained after the first-level cache unit is updated, and a specific determination method of the specified sequence number is not limited.

And step S103, generating a global serial number for the transaction service according to the attribute information and the designated serial number.

Optionally, generating a global serial number for the transaction service according to the attribute information and the specified sequence number includes: extracting the transaction time and the receiving end identification in the attribute information; and splicing the receiving end identification, the transaction time and the designated serial number in sequence to generate a global serial number aiming at the transaction service.

Specifically, when the transaction time is 20110213, the receiving end identifier is 0003, and the determined serial number which is matched with the withdrawal service and is valid is 0000000000000007, splicing is performed according to the sequence of the receiving end identifier, the transaction time and the specified serial number to obtain the serial number 0003201102130000000000000007, and the obtained serial number is used as the global serial number of the transaction service. It is to be understood that this embodiment is merely an example, and the specific contents of the designated serial number are not limited thereto.

According to the embodiment of the invention, after the attribute information of the transaction service is acquired, the specified serial number is directly acquired from the cache unit without being called from the database, and the global serial number is generated according to the attribute information and the sequence acquired from the cache, so that the strong dependence of the generation of the global serial number on the database is relieved, and the normal operation of the service is not influenced even under the condition that the database has short-term faults.

Example two

Fig. 2 is a flowchart of a method for generating a global serial number of a service according to a second embodiment of the present invention, where this embodiment further includes storing a transaction service associated with the global serial number in a database after generating the global serial number for the transaction service according to the attribute information and the specified sequence. As shown in fig. 2, the method includes:

step S201, acquiring attribute information of the transaction service.

Optionally, before obtaining the attribute information of the transaction service, the method further includes: acquiring a serial number in a specified range from a database; and respectively caching the serial numbers in the specified range into a first-level cache unit and a second-level cache unit, wherein the range of the serial numbers in the first-level cache unit is different from that in the second-level cache unit.

Optionally, the obtaining attribute information of the transaction service includes: identifying the transaction service received by the service receiving unit to obtain a service type; determining the transaction time of the transaction service received by the service receiving unit and the receiving end identification corresponding to the service receiving unit; and taking the service type, the transaction time and the receiving end identification as attribute information.

Step S202, obtaining the appointed serial number from the cache unit according to the service type of the transaction service.

Optionally, obtaining the specified sequence number from the cache unit according to the service type of the transaction service includes: inquiring from a first-level cache unit according to the service type to obtain a serial number matched with the service type; and judging whether the serial number matched with the service type is valid, if so, taking the serial number matched with the service type as an appointed serial number, otherwise, updating the serial number of the first-level cache unit, and acquiring the appointed serial number according to the updated first-level cache unit.

Optionally, the updating the sequence number of the first-level cache unit includes: judging whether the second-level cache unit contains the serial number, if so, directly writing the serial number in the second-level cache unit into the first-level cache unit so as to update the serial number of the first-level cache unit; otherwise, writing the serial number read from the database into the first-level cache unit and the second-level cache unit so as to update the serial numbers of the first-level cache unit and the second-level cache unit.

And step S203, generating a global serial number aiming at the transaction service according to the attribute information and the designated serial number.

Optionally, generating a global serial number for the transaction service according to the attribute information and the specified sequence number includes: extracting the transaction time and the receiving end identification in the attribute information; and splicing the receiving end identification, the transaction time and the designated serial number in sequence to generate a global serial number aiming at the transaction service.

And step S204, associating the transaction service with the global serial number to obtain an updated transaction service, and storing the updated transaction service in a database.

After the global serial number for the transaction service is generated, the transaction service and the global serial number are associated to obtain an updated transaction service, and the updated transaction service is stored in the database. The transaction service can be identified according to the global serial number during the execution of the transaction service in the distributed system.

It should be noted that, in the embodiment, after the transaction service after being further detailed is stored in the database, when the transaction service is executed in the distributed system, the related log in the execution process is also stored in the database. In the embodiment, the execution process of the transaction service is recorded by the pipelining recorder to generate the related log. After the updated transaction service is stored in the database, when the transaction service is executed completely, and when the whole execution process of the transaction service needs to be checked, the whole execution process of the transaction service can be acquired by inquiring in each distributed system through the global serial number. And when a certain system node in the distributed system has a fault, the fault occurrence point can be quickly positioned according to the global serial number. Therefore, in the embodiment, the transaction service associated with the global serial number is stored in the database, so that a user can conveniently acquire the transaction service associated with the global serial number from the database as required, and check and fault location are performed on the execution process of the transaction service in the distributed system according to the global serial number.

It should be noted that, in the database in the present embodiment, a plurality of kinds of information are stored, which are a pre-configured serial number, a transaction service associated with a global serial number, and a related log generated during the execution of the transaction service. The sequence number is mainly used for caching in a first-level cache unit and a second-level cache unit before the transaction business is formally operated; the transaction service primary related log associated with the global serial number is mainly used for identifying fault location in a primary operation process of the transaction service in a distributed system. It is to be understood that this embodiment is merely an example, and specific contents included in the database are not limited.

According to the embodiment of the invention, after the attribute information of the transaction service is acquired, the specified serial number is directly acquired from the cache unit without being called from the database, and the global serial number is generated according to the attribute information and the sequence acquired from the cache, so that the strong dependence of the generation of the global serial number on the database is relieved, and the normal operation of the service is not influenced even under the condition that the database has short-term faults. The transaction service associated with the global serial number is stored in the database, so that a user can conveniently acquire the transaction service associated with the global serial number from the database according to needs, and check and fault location are performed on the execution process of the transaction service in the distributed system according to the global serial number.
