Percona XtraDB Cluster 5.7 Documentation

Percona XtraDB Cluster is a database clustering solution for MySQL. It ensures high availability, prevents downtime and data loss, and provides linear scalability for a growing environment.

Features of Percona XtraDB Cluster include:

  • Synchronous replication: Data is written to all nodes simultaneously, or not written at all if it fails even on a single node.
  • Multi-master replication: Any node can trigger a data update.
  • True parallel replication: Multiple threads on slave performing replication on row level.
  • Automatic node provisioning: You simply add a node and it automatically syncs.
  • Data consistency: No more unsynchronized nodes.

Percona XtraDB Cluster is fully compatible with MySQL Server Community Edition, Percona Server, and MariaDB in the following sense:

  • Data compatibility: You can use data created by any MySQL variant.
  • Application compatibility: There is no or minimal application changes required.
This documentation is developed in Launchpad as part of the Percona XtraDB Cluster 5.7.
