-------------------------------------
Ozone 1.3.0 had been released and we currently have more than 600 open issues targeted for 1.3.0. I am moving the target field to 1.4.0.
What if anything needs to be discussed about the Target Version, Please reach out to me via Apache email or Slack.

> Key: HDDS-6822
> URL: https://issues.apache.org/jira/browse/HDDS-6822
> Project: Apache Ozone
> Issue Type: New Feature
> Components: Ozone Manager
> Reporter: Tanvi Penumudy
> Assignee: Tanvi Penumudy
> Priority: Major
> Attachments: HDDS - Allow Concurrent Writers in OM for OBS Bucket Key Paths_8Aug2022.pdf

>
> Presently only a single writer is allowed to {{applyTransaction()}} in {{OzoneManagerStateMachine}} which limits obtaining the maximum performance benefits from the HDDS-6402 {{KEY_PATH_LOCK}} optimization feature for the {{OBJECT_STORE}} bucket layout.
> The goal of this task is to expand the current functionality of a single threaded global executor service for executing a single write operation at a time by introducing multiple executors - a list of {{ThreadPoolExecutors}} of size configuration: {{om.num.concurrent.write.threads}} (= 10 by default) for allowing multiple concurrent write operations to be executed when they are each operating on disjoint key paths.
