Notable changes in 1.2.14
- Batchlog replay can be, and is throttled by default now.
See batchlog_replay_throttle_in_kb setting in cassandra.yaml.
Notable changes in 1.2.11
- Added a new consistency level, LOCAL_ONE, that forces all CL.ONE operations
to execute only in the local datacenter.
- New replace_address to supplant the (now removed) replace_token and
replace_node workflows to replace a dead node in place. Works like the
old options, but takes the IP address of the node to be replaced.
Notable changes in 1.2.9
- A history of executed nodetool commands is now captured.
It can be found in ~/.cassandra/nodetool.history. Other tools output files
(cli and cqlsh history, .cqlshrc) are now centralized in ~/.cassandra,
as well.
- A new sstablesplit utility allows to split large sstables offline.
- After performance testing for CASSANDRA-5727, the default LCS filesize
has been changed from 5MB to 160MB.
Notable changes in 1.2.5
- Custom secondary index support has been added to CQL3. Refer to
CQL3 documentation (http://cassandra.apache.org/doc/cql3/CQL.html)
for details and examples.

Cassandra is a widely deployed distributed structured database system.
Like Dynamo, Cassandra is eventually consistent. Like BigTable, Cassandra
provides a ColumnFamily-based data model richer than typical key/value
systems.
