Initial Release: Feb 25^th, 2016

• Build number:3
  • clustercontrol-1.2.12-1007
  • clustercontrol-cmonapi-1.2.12-156
  • clustercontrol-controller-1.2.12-1096
  • clustercontrol-nodejs-1.2.12-51
• Operational Reports (BETA). Generate, schedule and email out operational reports. The current default report shows a cluster’s health and performance at the time it was generated compared 1 day ago.
  • The report provides information on Node availability, Backup summary, Top queries, Host and Node stats. We will add more options and report types in future releases.
• Custom Advisor dialog. Create threshold based advisors with host or MySQL stats without needing to write your own JS script.
• Notification Services (new clustercontrol-nodejs package). Currently only email and pagerduty notifications are used by custom advisors. More to come.
• Local Mirrored Repository. Create a local mirror of a database vendor’s software repository. This allows you to freeze the current versions of the software packages used to provision a database cluster for a specific vendor and you can later use that mirrored repository to provision the same set of versions when adding more nodes or deploying other clusters.
• Export graphs as CSV, XLS files.
• Search the content in the system logs.
• MySQL based clusters
  • Galera
    • MariaDB 10.1 support.
    • Enable binary logging for a node. This node can then be used as the master for a replication slave or use the binary log for point in time recovery.
    • Delayed replication option when adding slave to the Galera Cluster. Delay the replication with N seconds.
    • Enable/Disable SSL encryption of Galera replication links.
  • MySQL Replication Master
    • Oracle MySQL 5.7 as vendor. Limitation: Percona Xtrabackup is not supported for MySQL 5.7 yet.
    • Semi-sync replication option.
    • Find the most advanced MySQL slave server to use for Master promotion.
  • MySQL Replication Slave
    • Delayed replication option (MySQL 5.6). Delay the replication with N seconds.
    • New table lists delayed replication slaves in the cluster.
  • New Backup options
    • Auto Select backup host. Allow ClusterControl to automatically select which node to take the backup on.
    • Enable backup failover node. If the selected backup node is down a failover node will be elected.
    • Galera: De-syncing a node with the highest local index and then used as the backup failover node.
    • MySQL Replication: Random slave node used as the backup failover node.
    • “No backup locks” for xtrabackup/innobackupex. Use FLUSH NO_WRITE_TO_BINLOG TABLES and FLUSH TABLES WITH READ LOCK instead of LOCK TABLES FOR BACKUP.
  • Configuration Management
    • Manage, Garbd and MaxScale configurations. Limitation: Maxscale does not support Reload (https://mariadb.atlassian.net/browse/MXS-99) meaning the operator must restart (e.g from the UI) the maxscale daemon.
• MongoDB
  • Support for MongoDB 3.2
• Postgres
  • Support for Postgres 9.5
