Summary: Optimize listStatus api in OzoneFileStatus
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
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.
