I have two years worth of data in SCs for the same reason as Mck. Having experienced the pain of the 0.6.x -> 0.7.x migration, I'm not thrilled about the idea of figuring out how to get all my data into a new format. No matter how much the C* community may despise SCs, a lot of people have a lot of data stored in them for valid reasons, so there needs to be a well-defined migration path. > refactor super column implmentation to use composite column names instead > ------------------------------------------------------------------------- > > Key: CASSANDRA-3237 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3237 > Project: Cassandra > Issue Type: Improvement > Reporter: Matthew F. Dennis > Priority: Minor > Labels: ponies > Fix For: 1.2 > > Attachments: cassandra-supercolumn-irc.log > > > super columns are annoying. composite columns offer a better API and performance. people should use composites over super columns. some people are already using super columns. C* should implement the super column API in terms of composites to reduce code, complexity and testing as well as increase performance. -- This message is automatically generated by JIRA.
