Jonathan Ellis commented on CASSANDRA-5403: ------------------------------------------- Rebased on top of trunk (post-5395-commit) and fixed some test errors: https://github.com/jbellis/cassandra/tree/5403-2 > Clean up ColumnFamily, ISortedColumns heirarchy > ----------------------------------------------- > > Key: CASSANDRA-5403 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5403 > Project: Cassandra > Issue Type: Bug > Reporter: Jonathan Ellis > Assignee: Jonathan Ellis > Fix For: 2.0 > > > CF wraps ISC but adds no real functionality of its own (post-supercolumn > cleanup). > This means that we're wasting allocations every time we create a CF/ISC pair > when really one would do. > Other things that would be nice to clean up: > # We often create an empty CF as a placeholder that should not be modified, > and rely on convention to avoid such modification. We could enforce this > with a new CF/ISC subclass. > # Many places still use TMBSC where ABSC would be adequate and cheaper > # Other places still (ModificationStatement; others?) would be fine using a > column container with no sorting requirement at all -- This message is automatically generated by JIRA.
