ProxySQL 1.4.13, released by ProxySQL, is now available for download in the Percona Repository along with an updated version of Percona’s proxysql-admin tool.
ProxySQL is a high-performance proxy, currently for MySQL and its forks (like Percona Server for MySQL and MariaDB). It acts as an intermediary for client requests seeking resources from the database. René Cannaò created ProxySQL for DBAs as a means of solving complex replication topology issues.
The ProxySQL 1.4.13 source and binary packages available at https://percona.com/downloads/proxysql include ProxySQL Admin – a tool, developed by Percona to configure Percona XtraDB Cluster nodes into ProxySQL. Docker images for release 1.4.13 are available as well: https://hub.docker.com/r/percona/proxysql/. You can download the original ProxySQL from https://github.com/sysown/proxysql/releases. GitHub hosts the documentation in the wiki format.
Improvements
- PSQLADM-53: Improved validation when
--write-nodeis used withproxysql-admin - PSQLADM-122: galera/node monitor log now reports the count of async slave nodes that are online.
Bugs Fixed
- PSQLADM-124: If the scheduler is configured with a –config-file that points to a file that doesn’t exist, the ERR_FILE was pointing to /dev/null. As a result, the user would not be notified about the error.
- PSQLADM-126:
proxysql-admincould show an error when--syncuserswas used and andmysql_userstable was empty. - PSQLADM-127:
proxysql_galera_checkercould corrupt the scheduler configuration after restart - PSQLADM-129: Stopping or restarting ProxySQL can lead to multiple instances of
proxysql_galera_checkerrunning at the same time
