[jira] Created: (CASSANDRA-1990) Store GC info once per SSTable

Store GC info once per SSTable
------------------------------

                 Key: CASSANDRA-1990
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1990
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Stu Hood
             Fix For: 0.8


Deleted columns are currently marked with the server time when they were deleted, but since it is not possible to perform GC at a resolution lower than an entire SSTable, it would probably make sense to remove the "markedForDeleteAt" field and use the SSTable flush time to indicate it.

It would make the most sense to tackle this during or soon after CASSANDRA-674.
