Announcing Cassandra 1.2.0

Datastax recently announced the release of Cassandra 1.2.0 and listed some of it's key improvements.  From the original post: 

Key improvements include:

• Virtual nodes, which improve the granularity of capacity increases and dramatically improve repair and rebuild times in larger clusters. See also this post on upgrading an existing cluster to vnodes.

• CQL3 improvements, notably the addition of collection types, queryable system information, and a CQL-native protocol.

• Request tracing is available to both CQL and classic Thrift requests, and can also be managed programatically.

• Atomic batches address the possibility of mid-batch coordinator failure.

• Configurable policies for disk failure

• Last but not least, many performance improvements to memory usage, column indexes, compaction, streaming, startup time, and more.
