> Optimize listStatus api in OzoneFileSystem
> ------------------------------------------
>
> Key: HDDS-1461
> URL: https://issues.apache.org/jira/browse/HDDS-1461
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Components: Ozone Filesystem, Ozone Manager
> Reporter: Lokesh Jain
> Assignee: Lokesh Jain
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.5.0
>
> Time Spent: 2h 20m
> Remaining Estimate: 0h
>
> Currently in listStatus we make multiple getFileStatus calls. This can be
> optimized by converting to a single rpc call for listStatus.
> Also currently listStatus has to traverse a directory recursively in order to
> list its immediate children. This happens because in OzoneManager all the
> metadata is stored in rocksdb sorted on keynames. The Jira also aims to fix
> this by using seek api provided by rocksdb.
