--------------------------------------
Summary: Add disk failure policy for hint/cache
Key: CASSANDRA-15404
URL: https://issues.apache.org/jira/browse/CASSANDRA-15404
Project: Cassandra
Issue Type: Improvement
Components: Local/Config
Reporter: maxwellguo
I use the default config to do some test. I delete all hint directory by
mistake，but my cassandra process at last stoped .Latter I found that that is
because the hint directory use the data disk policy .
In our production cluster , hint and cache's dir are set separately and are not
the same with data dir . And we know that cassandra can use multi data
directory to store data, the hint/cache's data operation should not affect the
data and commitlog 's read or write . Also
hint/cache 's data loss do not affect the cassandra's correct read .
so I think hint/cache's disk_faily_policy should be separately. So we can got
three type of
disk faily policy for : data disk , commitlog disk and hint/cache disk 。
I don't know if my suggestion is meaningful. If it is, I would like to take
over the issue。I'm also happy to receive new suggestions.
