Chen Luo resolved ASTERIXDB-2367.
---------------------------------
Resolution: Fixed
> Reduce Blocking when Create/Open/Delete Files from BufferCache
> --------------------------------------------------------------
>
> Key: ASTERIXDB-2367
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2367
> Project: Apache AsterixDB
> Issue Type: Improvement
> Reporter: Chen Luo
> Assignee: Chen Luo
> Priority: Major
>
> Currently, all files create/open/delete operations are all synchronized using
> the same object in buffer cache. Certain operations inside the synchronized
> block can be very expensive (e.g., sweepAndFlush and closeFile/openFile from
> IOManager) and thus block other operations.
