Ariel Weisberg updated CASSANDRA-9403:
--------------------------------------
Component/s: Testing
> Experiment with skipping file syncs during unit tests to reduce test time
> -------------------------------------------------------------------------
>
> Key: CASSANDRA-9403
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9403
> Project: Cassandra
> Issue Type: Test
> Components: Testing
> Reporter: Ariel Weisberg
> Assignee: Ariel Weisberg
> Fix For: 2.2.0 rc1
>
>
> Some environments have ridiculous outliers for disk syncing. 20 seconds
> ridiculous.
> Unit tests aren't testing crash safety so it is a pointless exercise.
> Instead we could intercept calls to sync files and check whether it looks
> like the sync would succeed. Check that the things are not null, mapped,
> closed etc. Outside of units tests it can go straight to the regular sync
> call.
> I would also like to have the disks for unit and dtests mounted with
> barrier=0,noatime,nodiratime to further reduce susceptibility to outliers. We
> aren't going to recover these nodes if they crash/restart.
