Distributed Database Capability ​

Availability ​

This feature is available since openGauss 2.1.0.

Introduction ​

This feature uses the distributed middleware shardingsphere to provide openGauss the distributed database capability. When 16 Kunpeng 920 (128 cores) nodes are used for networking (1 x shardingsphere-proxy, 7 x shardingsphere-jdbc, 8 x openGauss), the perfect sharding performance is greater than 10 million transactions per minute C (tpmC).

Benefits ​

A distributed database that logically has no resource restriction can be built over the middleware.

Description ​

With the sharding capability of shardingsphere, multiple openGauss databases can logically form a larger database with distributed transactions and elastic scaling capabilities. The usage method is the same as that of an openGauss database.

Enhancements ​

None.

Constraints ​

None.

Dependencies ​
