Percona Server version 5.1.50-rel12.1 RC 发布了。

功能性的改进包括:

  • Percona Server 5.1.50-rel12.1 基于 MySQL 5.1.50.
  • 新增的特性:
    • innodb_lru_dump_restore – Implemented automatic dumping of the buffer pool at specified intervals.
    • innodb_buffer_pool_shm – Implemented option ”innodb_buffer_pool_shm_checksum”; when enabled, shared memory buffer pool is checksum validated. This change also fixed these bugs: #643724, #649408, and #649393. (Yasufumi Kinoshita)
    • innodb_expand_import – Implemented more exact checking to avoid corruption of the ”.ibd” file using ”innodb_expand_export”. (Yasufumi Kinoshita)
