--------------------------------------------------------------------
The patch works as intended. To specify a particular ks/cf to be archived we
need to add parameters when starting cassandra.
{code}
./cassandra -Dcassandra.readKeyspaceCommitlog=exampleKS
-Dcassandra.readColumnFamilyCommitlog=exampleCF
{code}
Maybe it would be a better option to add restore_keyspace and
restore_columnfamily config options to commitlog_archiving.properties. If the
original setup is preferable I'll rebase the patch (it doesn't apply cleanly
because of other changes on the branch).
The last thing I want to change is: The patch assumes that users will want to
replay only part of the commitlog, we should still allow them to replay the
entire log if the ks/cf parameters aren't supplied.
