Planet Cassandra is proud to announce the anticipated release of Apache Cassandra version 1.2.0.
Key Improvements found in C* 1.2.0
- 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.
