  • This is a our best release yet for Postgres with a number of improvements.
    • Create a new Postgres Node/cluster from the “Create Database Node” dialog or add an new node with a few click.
    • You can now easily add a new replication slave for your Postgres master node.
    • The replication peformance and status is shown on the overview page for the slave.
    • You can restore a backup created by ClusterControl on a specific node.
    • Create your own dashboard with stats to chart/graph on the overview page like MySQL based clusters.
    • DB performance charts on the Nodes page.
    • View database status and variables on your postgres nodes side by side.
    • Enabled DevStudio, i.e., our JavaScript based advisors which was introduced in 1.2.10 for Postgres as well.
    • Create your own postgres advisors/DB minions for alarms or email notifications.
  • MaxScale for MySQL based clusters. MariaDB MaxScale is an open-source, database-centric proxy that works with MariaDB Enterprise, MariaDB Enterprise Cluster, MariaDB 5.5, MariaDB 10 and Oracle MySQL.
    • Deploy MaxScale instance for round-robin or read/write splitter with a customizable configuration.
    • Add an existing running MaxScale instance.
    • Send commands to max admin and view the output in ClusterControl.
  • MySQL Based Clusters.
    • You can now use CoderShip as the Galera vendor for Create Cluster and Database node.
    • Create a MySQL Replication Master Node from the Create DB Node dialog. Currently only Percona as vendor is supported.
    • Add/Register an existing running MySQL slave without stopping and provisioning the dataset from the cluster.
    • Create Cluster and Database Node now support using “internal repositories” for environments where you do not have internet access and have internal repostory servers instead.

    • Fixes to Clone Cluster and the UI notification system/look.
    • Backup individual schemas.
    • Option to enable ‘wsrep_desync’ during backup for Galera clusters to workaround stalls/issues with FLUSH TABLES WITH READ LOCK. Puts the backup node into ‘Donor/Desynced’ state during the backup.
    • Manage Email Notifications for all users at once
    • New Database Logs page
      • We have a new page specifically for database logs that you access from Logs →Database Logs.
      • A tree view lists your DB nodes so you can simply pick the nodes that you want to check the mysql error log for
    • Revamped Configuration Management.
      • New implementation and look using our JS engine and a set of js scripts.
      • Group Changes. Automatically change and persist individual database variables across your DB nodes at once. If it’s a dynamic variable we’ll change it directly on the nodes.
    • Revamped MySQL User Management.
      • New implementation and look using our JS Engine and a set of js scripts.
      • We’ removed the old implementation where we maintained users created from ClusterControl separately.
      • Users and privileges are set directly and retrieved from your cluster so you are always in sync.
      • Create your users across more than one cluster at once.
  • HAProxy and KeepAlived
    • You can now add existing running HAProxy and Keepalived instances that have been installed outside of ClusterControl.
