[jira] [Created] (CASSANDRA-5988) Make hint TTL customizable

Oleg Kibirev created CASSANDRA-5988:
---------------------------------------

             Summary: Make hint TTL customizable
                 Key: CASSANDRA-5988
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5988
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Oleg Kibirev


Currently time to live for stored hints is hardcoded to be gc_grace_seconds. This causes problems for applications using backdated deletes as a form of optimistic locking. Hints for updates made to the same data on which delete was attempted can persist for days, making it impossible to determine if delete succeeded by doing read(ALL) after a reasonable delay. We need a way to explicitly configure hint TTL, either through schema parameter or through a yaml file.
