Christian Spriegel commented on CASSANDRA-11301:
------------------------------------------------
Benedict: CASSANDRA-9240 does not specify 2.1 as fixVersion. Am I correct to
assume that 2.1 should not be affected by this?
[~luxifer]: Didn't you say that our 2.1 installation is also affected? Did you
test with setcompactionthroughput?

> Project: Cassandra
> Issue Type: Bug
> Components: Core

> 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.
