[jira] [Created] (CASSANDRA-14261) Compaction Profiling Improvements

Jeff Jirsa created CASSANDRA-14261:
--------------------------------------

             Summary: Compaction Profiling Improvements
                 Key: CASSANDRA-14261
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14261
             Project: Cassandra
          Issue Type: Improvement
          Components: Compaction
            Reporter: Jeff Jirsa
            Assignee: Jeff Jirsa
             Fix For: 4.x


There's some low hanging fruit in some laptop compaction runs, such as creating a ton of the same object unnecessarily and hashing cell names repeatedly to see if a column is dropped even when we should know that the table has no dropped columns.
