Major gaps for Trove as production grade DBaaS solution

● Provision MySQL HA○ Percona XtraDB cluster○ MySQL Replication

● Support NoSQL DB clusters○ MongoDB○ Cassandra○ Redis○ CouchDB○ CouchBase

● In-memory databases○ MemCached○ VoltDB

● Backup/restore of cluster databases

Conclusion

● Currently supports only single instance MySQL database

● Cluster and HA support is under design● Immature architecture (tightly coupled modules,

direct access to database from DB VM, interfaces between modules are not defined)

● Under active development
