The Cassandra team is very pleased to announce the release of Apache Cassandra
version 1.1.0. Cassandra 1.1.0 is a new major release for the Apache Cassandra
distributed database. This version adds numerous improvements[1,2], amongst
which:
- Schema updates have been reworked and conflict from concurrent updates
are now automatically resolved[4]
- It introduces a new major revision of the Cassandra Query Language:
CQL v3.0[5], even though CQL 2.0 is still supported and the default.
- Updates within a row are now made in isolation[6].
- Finer-grained control over data directories placement[7].
- Global row and key caches for easier configuration
- And much more...
And as is the rule for some time now, rolling upgrades from previous versions
are supported, but make sure to have a look at the release notes[2] before
upgrading.
Both source and binary distributions of Cassandra 1.1.0 can be downloaded at:
http://cassandra.apache.org/download/
Or you can use the debian package available from the project APT repository[3]
(you will need to use the 11x series).
