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
