There are no incompatibilities with respect to S3. This feature can be enabled only together with ozone.om.enable.filesystem.paths. When file system-style path handling is enabled, 100 % s3 compatibility could not be guaranteed. FS compatible s3 key names supposed to be working well, but non-fs compatible, extra key names (like 'a/../b1 or real file with the name `key1/` might be normalized or rejected by the implementation of ozone.om.enable.filesystem.paths.)
TODONote: Added S3 acceptance test when with feature is turned on ?- PREFIX layout.

Done testing to evaluate the performance of delete, rename operations in feature branch vs master code base. Following charts capturing the directory delete and rename operations execution time shows that, feature branch has a very significant performance gain compared to the master.
Ran freon 'dtsg' dfs tree generator benchmark test in a single node cluster. V0 represents master code(simple) and V1 represents feature branch(prefix). Please refer to the Jira document for more details.
