A kind of server and data processing method

Abstract

The invention relates to computer communication technology, in particular to a server and a data processing method to simply realize transaction management in a cloud service scenario. The second data server provided by the embodiment of the present invention is connected to the application server and the first data server in the cloud, and receives the first operation request sent by the application server for requesting the first persistence layer service provided by the first data server. In the request Including at least one operation belonging to the same transaction; the transaction management module in the second data server performs the at least one operation on the second data in itself; the second data is the same as the first data in the first data server; if the operation If all are executed successfully, a second operation request is generated to request to perform the above at least one operation on the first data and send it to the first data server. By providing persistence layer services with transaction management functions between application services and cloud services, application services are not required to implement transaction management, reducing the complexity of application services.

Description

technical field [0001] The invention relates to computer communication technology, in particular to a server and a data processing method. Background technique [0002] In the traditional database transaction management technology, the execution of data operations is usually divided into three steps: pre-submission, submission, and rollback when the data operation fails. Among them, "pre-commit" means that all operations in the transaction are executed in the cache. If all operations are successful, then "commit", otherwise "rollback"; "commit" means writing data to the database; "rollback" is Refers to clearing the cache and restoring the data before pre-submission. [0003] The persistence layer service is used to shield different database deployment forms, version differences and / or database providers, and provides a unified interface for applications to access the database. [0004] figure 1 It shows a typical architecture for providing persistence layer services to a...

Problems solved by technology

At this time, if the persistence layer service itself implements the transaction management function, it needs to consume additional data processing resources. When the occupied data processing resources are large, if the data processing resources available for the persistence layer service are limited, the persistence layer service may be self influence

[0006] Therefore, in the current cloud service scenario, developers of different application services usually need to provide their own transaction management functions, resulting in high complexity of application development. At the same time, the transaction management functions of different applications are quite different, and compatibility is difficult to guarantee
