-----------------------------------------

             Summary: Implement better way of eliminating compaction left overs.
                 Key: CASSANDRA-5151
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5151
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 1.1.3
            Reporter: Yuki Morishita
             Fix For: 1.2.1


This is from discussion in CASSANDRA-5137. Currently we skip loading SSTables that are left
over from incomplete compaction to not over-count counter, but the way we track compaction
completion is not secure.

One possible solution is to create system CF like:

{code}
create table compaction_log (
  id uuid primary key,
  inputs set<int>,
  outputs set<int>
);
{code}

to track incomplete compaction.
