Information	Description
Release date	May 15, 2024

Commit number	38166dc
OBServer RPM version	oceanbase-ce-4.2.1.6-106000012024042515

Performance optimization

Optimization of show table status performance: In earlier versions, the performance of the show table status from ... like ... command is not ideal because it did not make use of indexes related to table_name. In the new version, significant improvement in query performance has been achieved for scenarios with single table filtering conditions.

Bug fixes

Fixed the issue where after SET collation_connection = 'utf8mb4_unicode_ci' is executed, comparing/joining columns of string type in information_schema would cause an error Illegal mix of collations, which is not compatible with native MySQL.
Fixed the issue where reading and writing LOB data during the upgrades while running both the old and new versions could lead to OBServer core dump.
Fixed the memory leak issue caused by asynchronous query timeouts in OBKV.

性能优化

优化 show table status 性能： 老版本 show table status from ... like ... 场景性能较差，未利用 table_name 相关索引。新版本针对存在单表过滤条件的场景，显著提升查询性能。

缺陷修复

修复 SET collation_connection = 'utf8mb4_unicode_ci' 后，information_schema 下字符串类型的列比较/关联操作，会报错 Illegal mix of collations，和原生 MySQL 不兼容的问题。
修复升级混跑过程中读写 LOB 数据可能导致 OBServer Core 的问题。
修复 OBKV 异步查询超时后导致内存泄漏的问题。
