[jira] [Created] (CASSANDRA-5487) Promote row-level tombstones to index file

Jonathan Ellis created CASSANDRA-5487:
-----------------------------------------

             Summary: Promote row-level tombstones to index file
                 Key: CASSANDRA-5487
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5487
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.2.0
            Reporter: Jonathan Ellis
             Fix For: 2.0


The idea behind promoted indexes (CASSANDRA-2319) was we could skip a seek to the row header by keeping the column index in the index file.  But, we left row-level tombstones in the data file, so we still need to seek to read that.

A related note: IndexedSliceReader is some hellishly complex code.  If we can simplify that at all, angels will weep tears of joy.
