> RBF: File based state stores should allow concurrent access to the records
> --------------------------------------------------------------------------
>
> Key: HDFS-16967
> URL: https://issues.apache.org/jira/browse/HDFS-16967
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
> Labels: pull-request-available
>
> File based state store implementations (StateStoreFileImpl and
> StateStoreFileSystemImpl) should allow updating as well as reading of the
> state store records concurrently rather than serially. Concurrent access to
> the record files on the hdfs based store seems to be improving the state
> store cache loading performance by more than 10x.
> For instance, in order to maintain data integrity, when any mount table
> record(s) is updated, the cache is reloaded. This reload operation seems to
> be able to gain significant performance improvement by the concurrent access
> of the mount table records.
