Open Stack

Hi Arunkumar,

Unfortunately, for now Trove only supports MySQL and MariaDB, I'm working
on adding PostgreSQL support. All other datastores are unmaintained right
now.

Since this(Victoria) dev cycle, docker container was introduced in Trove
guest agent in order to remove the maintenance overhead for multiple Trove
guest images. We only need to maintain one single guest image but could
support different datastores. We have to do that as such a small Trove team
in the community.

If supporting Redis, Cassandra, MongoDB or Couchbase is in your feature
request, you are welcome to contribute to Trove.

Please let me know if you have any other questions. You are also welcome to
join #openstack-trove IRC channel for discussion.
