[jira] [Created] (HDDS-6822) Allow Concurrent Writers in OM for OBS Bucket Key Paths
Tanvi Penumudy created HDDS-6822:
------------------------------------
Summary: Allow Concurrent Writers in OM for OBS Bucket Key Paths
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
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.
