    Multi-source replication Any node can trigger a data update.
    True parallel replication Multiple threads on replica performing replication on row level
    Automatic node provisioning You simply add a node and it automatically syncs.
    Data consistency No more unsynchronized nodes.
    PXC Strict Mode Avoids the use of tech preview features and unsupported features
    Configuration script for ProxySQL Percona XtraDB Cluster includes the proxysql-admin tool that automatically configures Percona XtraDB Cluster nodes using ProxySQL.
