Optimize recursive ozone filesystem apis
URL: https://github.com/apache/hadoop/pull/718#issuecomment-482218542
Hi @lokeshj1703
Thanks for the patch.
We want to convert all OM requests in 2 phase for HA. So that in
applyTransaction it should be just applied to OM DB. So, that read from OM DB
is not required during applyTransaction and also followers can just apply to OM
DB.(No additional changes required). And also this helps in future if we want
to batch transactions and then commit to OM DB also. Another advantage is all
requests will be executed only on the leader OM, if any errors like volume not
found, bucket not found etc., will not be written to raft log, as we return the
startTransaction with exception.
For more info refer HDDS-1393 and HDDS-1379. If you think any other approach
let us know.

> This Jira aims to optimise recursive apis in ozone file system. These are the
> apis which have a recursive flag which requires an operation to be performed
> on all the children of the directory. The Jira would add support for
> recursive apis in Ozone manager in order to reduce the number of rpc calls to
> Ozone Manager. Also currently these operations are not atomic. This Jira
> would make all the operations in ozone filesystem atomic.
