Features

Trove is moving fast in terms of the features being added in the various releases. In this section, we will take a look at the features of three releases: the current release and the past two.

The Juno release

The Juno release saw a lot of features being added to the Trove system. Here is a non-exhaustive list:

• Support for Neutron: Now we can use both Nova-network and Neutron for networking purposes.
• Replication: MySQL master/slave replication was added. The API also allowed us to detach a slave for it to be promoted.
• Clustering: MongoDB cluster support was added.
• Configuration group improvements:
  • The functionality of using a default configuration group for a datastore version was added. This allows us to build the datastore version with a base configuration of your company standards.
  • Basic error checking was added to configuration groups.

The Kilo release

The Kilo release majorly worked on introducing a new datastore. The following is the list of major features that were introduced:

• Support for the GTID (short for global transaction identifier) replication strategy
• New datastores, namely Vertica, DB2, and CouchDB, are supported

The Liberty release

The Liberty release introduced the following features to Trove. This is a non-exhaustive list:

• Configuration groups for Redis and MongoDB
• Cluster support for Redis and MongoDB
• Percona XtraDB cluster support
• Backup and restore for a single instance of MongoDB
• User and database management for MongoDB
• Horizon support for database clusters
• A management API for datastores and versions
• The ability to deploy Trove instances in a single admin tenant so that the Nova instances are hidden from the user
