Tommaso Teofili commented on OAK-6710:
--------------------------------------
I think this can be resolved. There's a bit more work to be done to address
reindexing case better, but I'll track in another issue.
> CommitMitigated merge policy should not reduce performance significantly

> Key: OAK-6710
> URL: https://issues.apache.org/jira/browse/OAK-6710
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: lucene
> Affects Versions: 1.7.7
> Reporter: Vikas Saurabh
> Assignee: Tommaso Teofili
> Labels: performance, scalability
> Fix For: 1.8
>
>
> While running performance tests (internally) using latest unstable releases
> having {{CommitMitigatedTieredMergePolicy}} we observed significant drop in
> performance (OAK-6704).
> The policy, although bad for performance, showed dramatic drop in churn
> created in data store size. So, clearly, OAK-5192 did what it intended to do.
> Opening this issue to factor in drop in performance and then set the default
> back to {{CommitMitigatedTieredMergePolicy}}.
