[jira] [Created] (CASSANDRA-11301) Non-obsoleting compaction operations over compressed files can impose rate limit on normal reads

Benedict created CASSANDRA-11301:
------------------------------------

             Summary: Non-obsoleting compaction operations over compressed files can impose rate limit on normal reads
                 Key: CASSANDRA-11301
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11301
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Benedict
             Fix For: 2.2.6


Broken by CASSANDRA-9240; the rate limiting reader passes the ICompressedFile interface to its parent, which uses this to attach an "owner" - which means the reader gets recycled on close, i.e. pooled, for normal use. If the compaction were to replace the sstable there would be no problem, which is presumably why this hasn't been encountered frequently. However validation compactions on long lived sstables would permit these rate limited readers to accumulate.
