JDBC Client Load Balancing and Read/Write Isolation

Availability

This feature is available since openGauss 2.1.0.

Introduction

The JDBC client provides load balancing and read/write isolation capabilities.

Benefits

Load balancing and read/write isolation can be configured on the JDBC client.

Description

The IP addresses and port numbers of multiple nodes on the client are configured to adapt to HA switchover between multiple AZs and remote DR switchover. The connection-level read/write isolation configuration is supported. Preferentially connecting to read-only nodes is supported. Multiple read-only nodes are evenly distributed.
