[jira] [Commented] (CASSANDRA-9839) Move crc_check_chance out of compressions options

["Aleksey Yeschenko (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-9839?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14653366#comment-14653366 ] 

Aleksey Yeschenko commented on CASSANDRA-9839:
----------------------------------------------

The important part here is fixing {{CFS.setCrcCheckChance()}}, and that is why it's labeled 3.0.

If we could fix syntax and schema as well, it would be nice (less ugly compatibility code to carry through 3.X), but it's not critical.

> Follow up to CASSANDRA-8384. The option doesn't belong to compression params - it doesn't affect compression, itself, and isn't passed to compressors upon initialization.
> While it's true that it is (currently) only being honored when reading compressed sstables, it still doesn't belong to compression params (and is causing CASSANDRA-7978 -like issues).
> [~tjake] suggested we should make it an option of its own, and I think we should.
