------------------------------------
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.
