Is MySQL Cluster (which uses the NDB engine) supported with JBoss SOA-P?

Issue

• We identified as a single point of failure the SOADB schema. This schema use elements, which are not compatible with MySQL NDB (clustered) engine like foreign keys. Please, recommend a full clustered solution / how to solve high availability for SOADB schema- preferably with MySQL.
• We want to use the SOA Platform with MySQL Cluster, which uses the NDB engine instead of the standard InnoDB engine. Is this a certified configuration for the SOA Platform 5.1 ?
