Way back in Nov 09, we did a users survey and asked what features people wanted to see. Here was my summary of the responses: http://www.mail-archive.com/cassandra-user@incubator.apache.org/msg01446.html
Looking at that, we've done essentially all of them. I think we can make a strong case that our next release should be 1.0; it's production ready, it's reasonably feature-complete, it's documented, and we know what our upgrade path story is. The list-- Load balancing: basics done; https://issues.apache.org/jira/browse/CASSANDRA-1427 is open to improve it Decommission: done Map/reduce support: done ColumnFamily / Keyspace definitions w/o restart: done Design documentation: started at http://wiki.apache.org/cassandra/ArchitectureInternals Insert multiple rows at once: done Remove_slice_range / remove_key_range: turned out to be a *lot* harder than it looks at first. Postponed indefinitely. Secondary indexing: done Caching: done (with some enhancements possible such as https://issues.apache.org/jira/browse/CASSANDRA-1969 and https://issues.apache.org/jira/browse/CASSANDRA-1956) Bulk delete (truncate): done I would add, User documentation: done (http://www.riptano.com/docs) Large row support: done Improved replication strategies and more sophisticated ConsistencyLevels: done Efficient bootstrap/streaming: done Flow control: done Network-level compatibility between releases: scheduled (https://issues.apache.org/jira/browse/CASSANDRA-1015) -- Jonathan Ellis Project Chair, Apache Cassandra co-founder of Riptano, the source for professional Cassandra support http://riptano.com
