Percona XtraDB Cluster 5.7.14-26.17 GA New Features

This is a list of the most important features introduced in Percona XtraDB Cluster 5.7 compared to version 5.6:

  • PXC Strict Mode saves your workload from experimental and unsupported features.
  • Support for monitoring Galera Library instruments and other wsrep instruments as part of Performance Schema.
  • Support for encrypted tablespaces in Multi-Master Topology, which enables Percona XtraDB Cluster to wire encrypted tablespace to new booting node.
  • Compatibility with ProxySQL, including a quick configuration script.
  • Support for monitoring Percona XtraDB Cluster nodes using Percona Monitoring and Management
  • More stable and robust operation with MySQL and Percona Server version 5.7.14, as well as Galera 3.17 compatibility. Includes all upstream bug fixes, improved logging and more.
  • Simplified packaging for Percona XtraDB Cluster to a single package that installs everything it needs, including the Galera library.
  • Support for latest Percona XtraBackup with enhanced security checks.
Bug Fixes
  • Fixed crash when a local transaction (such as EXPLAIN or SHOW) is interrupted by a replicated transaction with higher priority (like ALTER that changes table structure and can thus affect the result of the local transaction).

  • Fixed error message when altering non-existent table with pxc-strict-mode enabled.
  • Fixed path to the directory in percona-xtradb-cluster-shared.conf.
  • Fixed setting of seqno in grastate.dat to -1 on clean shutdown.
  • Fixed failure of asynchronous TOI actions (like DROP) for non-primary nodes.
  • Fixed replacing of my.cnf during upgrade from 5.6 to 5.7.
