Alpha Percona Xtradb Cluster release Not ready for production use

pxc-release is a BOSH release of MySQL Galera that can be used as a backing store for Cloudfoundry. The Galera Cluster Provider is Percona Xtradb Cluster. This release is intended as a drop-in replacement for cf-mysql-release.

Components

MySQL Server

Proxy

Traffic to the MySQL cluster is routed through one or more proxy nodes. The current proxy implementation is Switchboard. This proxy acts as an intermediary between the client and the MySQL server, providing failover between MySQL nodes. The number of nodes is configured by the proxy job instance count in the deployment manifest.

NOTE: If the number of proxy nodes is set to zero, apps will be bound to the IP address of the first MySQL node in the cluster. If that IP address should change for any reason (e.g. loss of a VM) or a proxy was subsequently added, one would need to re-bind all apps to the IP address of the new node.

For more details see the proxy documentation.
