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.
  • Atomic batches address the possibility of mid-batch coordinator failure.
  • Last but not least, many performance improvements to memory usage, column indexes, compaction, streaming, startup time, and more.
