Subject [jira] [Commented] (CASSANDRA-9517) Switch to DTCS for hint storage
Date Fri, 29 May 2015 21:18:18 GMT


Albert P Tobey commented on CASSANDRA-9517:

The big question is if we can get away without the major compaction and it sounds like that's
not feasible at this point. A new, simple compaction strategy that does no merging and only
tombstone cleanup might be the best bet in the short term.

>             Fix For: 2.1.6
> The DateTieredCompactionStrategy is a good choice for HintedHandoff so that we reduce
the compaction load we incur when users build up hints.  [] and others
have tried the following patch in various setups and have seen significantly less load from
hint compaction.
> Setting the time window to 10 minutes has shown additional improvement.
> [~krummas] do you have any feedback about this idea and/or settings?
