New Features in Cassandra 0.7

Gary Busbabek, of Rackspace, has a post discussing the upcoming features in the 0.7 release of Cassandra. There are some major changes/improvements in store for 0.7.

Here are the big ones:

• Memory Efficient Compactions (CASSANDRA-16) - Compactions will now happen incrementally
• Online Schema Changes (CASSANDRA-44)
  • Exposes the ability to create and drop column families and keyspaces from its client API.
  • Using the same methods there is limited support for updating existing column families and keyspaces (e.g., increasing the replication factor for a particular keyspace)
• Secondary Indexes (CASSANDRA-749)
  • Secondary indexes are now maintained by Cassandra, no more hand built secondary indexes.
  • Using the API for online schema changes, secondary indexes can be added to existing or brand new column families

In addition to the major changes there are several improvements to the streaming code, improved read performance, support for Thrift 0.5 among many other items. As with every release things can change so be sure to read the changelog for the most up to date information about the release.
