Problems solved by technology

However, in this case, since the client segmentation rules are hard-coded, when re-segmenting the MYSQL database, all client segmentation rules need to be changed, making it almost impossible to re-segment the MYSQL database
[0006] In addition, regardless of the MYSQL proxy scheme with dispatch rules or the client dispatch scheme, data migration will be difficult
Moreover, during the migration process, the service of the entire database cluster needs to be stopped, which has a great impact on the business

Abstract

The invention provides a MySQL database horizontal-sharding method. The method includes: distributing a data ID range (Min(n), Max(n)) for a database in a database cluster according to a preset data ID range distribution strategy; and storing MySQL data to each database with the data ID range including data IDs according to the data IDS of the MySQL data. The letter N is a total of the databases in the database cluster, the Min(n) is a minimum boundary value of the data ID range of the n-th database, and the Max(n) is a maximum boundary value of the data ID range of the n-th database. Through the method, the MySQL databases can be sharded and transferred flexibly and extensibility is improved.

Description

technical field [0001] The invention relates to the field of MYSQL data storage, and more specifically, to a MYSQL database horizontal switching method, a MYSQL connection establishment method and a device. Background technique [0002] As the data stored in MYSQL becomes larger and larger, one MYSQL database cannot store all the data, so the data will inevitably be stored in several MYSQL databases, which requires database sharding. [0003] Database segmentation methods mainly include two types: vertical segmentation and horizontal segmentation. Straight splitting refers to splitting different columns in the database and storing them in different MYSQL databases. Horizontal splitting refers to splitting different rows in the database and storing them in different databases. Since vertical splitting does not have good scalability, horizontal splitting is usually used when splitting MYSQL databases. [0004] At present, the representative open source horizontal segmentati...
