Abstract

The invention relates to a multi-database data processing method, a multi-database data processing device, a storage medium and electronic equipment. The method comprises the steps of acquiring a first operating request and a second operating request separately corresponding to a first database and a second database; executing a first data operation on the first database according to the first operating request; when a preset method in a preset cache is called to judge that concurrent operations do not exist currently, storing operating content information of the second operating request to the preset cache; and calling the operating content information from the preset cache, and executing a second data operation on the second database via a preset Java multi-thread pool. According to themethod, device, medium and equipment provided by the invention, the data consistency problem of the multiple databases is solved by using a technology based on the cache and the multiple threads, thedisadvantages of processing in an MQ message manner are avoided, and thus the data consistency of the multiple databases is relatively good.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a multi-database data processing method, a multi-database data processing device, and a computer-readable storage medium and electronic equipment for realizing the multi-database data processing method. Background technique [0002] At present, with the large and rapid growth of the amount of data stored in the database and the amount of data access, there will be more and more tables in the database with the development of time and business without sub-database sub-tables. The amount of data will also increase. Correspondingly, the overhead of data manipulation, addition, deletion, modification and query will also increase. In addition, since distributed deployment cannot be performed, and the resources of a server are limited, the amount of data that the database can carry and the data processing capacity will eventually encounter bottlenecks. [0003] In order...
