Percona XtraDB Cluster 5.7 Documentation
Percona XtraDB Cluster is a high-availability solution for MySQL.
It ensures the highest possible uptime,
prevents 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.

There is no or minimal application changes required.
