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

             Summary: nodetool compactionhistory can allocate memory unbounded
                 Key: CASSANDRA-8112
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8112
             Project: Cassandra
          Issue Type: Bug
            Reporter: T Jake Luciani
            Priority: Minor
             Fix For: 2.1.1


nodetool compactionhistory keeps data for 1 week by default and creates a table 
from the result set in memory.

For many systems a week can generate 10's of thousands of compactions (esp with 
LCS) we should guard against this command allocating too much memory.
