Percona XtraDB Cluster 5.7.17-27.20 发布了,二进制文件可在 下载区 或 软件仓库 中下载。

Percona XtraDB Cluster 5.7.17-27.20 基于以下这些项目:

  • Percona Server 5.6.42

  • Codership WSREP API release 5.6.42

  • Codership Galera library 3.25

Fixed Bugs

  • PXC-2281: Debug symbols were missing in Debian dbg packages.

  • PXC-2220: Starting two instances of Percona XtraDB Cluster on the same node could cause writing transactions to a page store instead of a galera.cache ring buffer, resulting in huge memory consumption because of retaining already applied write-sets.

  • PXC-2230rgcs.fc_limit=0 not allowed as dynamic setting to avoid generating flow control on every message was still possible in my.cnf due to the inconsistent check.

  • PXC-2238: setting read_only=1 caused race condition.
