Percona XtraDB Cluster 5.6.15-25.5 发布了,该版本基于 Percona Server 5.6.15-63.0,改进记录包括:

New Features

  • wsrep patch did not allow server to start with Query Cache enabled. This restriction and check have been removed now and query cache can be fully enabled from config file.

  • New SST options have been implemented: inno-backup-opts, inno-apply-opts, inno-move-opts which pass options to backup, apply and move stages of innobackupex.

  • The joiner would wait and not fall back to choosing other potential donor nodes (not listed in wsrep_sst_donor) by their state. This happened even when comma was added at the end. This fixes it for that particular case. Bug fixed #1285380.

  • Initial configurable timeout, of 100 seconds, to receive a first packet via SST has been implemented, so that if donor dies somewhere in between, joiner doesn’t hang. Timeout can be configured with the sst-initial-timeout variable.

Bugs fixed

  • Replication of partition tables without binlogging enabled failed, partition truncation didn’t work because of lack of TO isolation there. Bug fixed #1219605.

  • Using LOAD DATA INFILE in with autocommit set to 0 and wsrep_load_data_splitting set to ON could lead to incomplete loading of records while chunking. Bug fixed #1281810.

  • Garbd could crash on CentOS if variable gmcast.listen_addr wasn’t set. Bug fixed #1283100.

  • Node couldn’t be started with wsrep_provider_options option debug set to 1. Bug fixed #1285208.

  • Boostrapping a node in a NON-PRIMARY state would lead to crash. Bug fixed #1286450.

  • New versions of xtrabackup SST scripts were ignoring --socket parameter passed by mysqld. Bug fixed #1289483.

  • Regression in Galera required explicitly setting socket.ssl to Yes even if you set up variables socket.ssl_key and socket.ssl_cert. Bug fixed
