Version information
Release date: June 30, 2022
Version: V2.2.10
Overview
OceanBase Connector/J V2.2.10 introduces the LoadBalance feature and enhances compatibility with MySQL and Oracle. It is suitable for general business use.
Feature enhancements
Added the LoadBalance feature. Users can specify connection balancing methods (random, weighted, or round-robin) via a URL or configuration file to establish connections. Load balancing groups and blocklist policies have also been expanded to improve availability and security.
Added support for the
sendConnectionAttributesinterface to control whether extended attributes are sent during connection establishment, meeting the need to provide more options for users with different permissions.
Bug fixes
Fixed an issue where the getWarnings() method returned null when an error occurred in MySQL-compatible mode.
Fixed an inconsistency between the ColumnType of the Blob and Text types and MySQL-compatible mode in MySQL-compatible mode.
Fixed an inconsistency between the behavior of the Statement checkClose() method and MySQL-compatible mode when closing a connection in MySQL-compatible mode.
Fixed an issue where the ResultSet.close() method did not implement cursor closure logic when using a refcursor in Oracle-compatible mode, potentially leading to untimely release of cursors in OceanBase Database under certain circumstances.
Fixed a potential lock issue triggered by the setTransactionIsolation method.
