Abstract

The invention discloses a data synchronization method and device for a relational database. The method comprises the following steps that: receiving data to be processed, and storing the data to be processed into a preset cache space; when a data synchronization request is received, extracting data on batch from the preset cache space, wherein the data synchronization request is a request for synchronizing the emitted data to the relational database according to a preset time period; determining data to be synchronized from the data extracted on batch; and synchronizing the data to be synchronized to the relational database. Through the method, the problem of low batch processing ability of a system in the relevant art is solved.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a data synchronization method and device for a relational database. Background technique [0002] With the in-depth application of big data, batch processing capability and high concurrency capability have become one of the important indicators of system performance. Relational data plays an indispensable role in applications. However, for relational databases, it lags behind big data distributed cluster systems in terms of batch processing and high concurrency. For non-real-time or low-real-time requirements, usually directly connect to the database and perform data storage operations. In a high-concurrency distributed operating system, this processing will encounter various deadlocks and connection timeouts. The other is to process data asynchronously through message queues. While the processing capacity and concurrency are improved, this requires the system to have high fau...
