[GitHub] [ozone] tanvipenumudy opened a new pull request, #3664: HDDS-7107. Determine OzoneManagerStateMachine multipleExecutors index via hashing
tanvipenumudy opened a new pull request, #3664:
URL: https://github.com/apache/ozone/pull/3664
## What changes were proposed in this pull request?
[To be merged after [HDDS-7105](https://issues.apache.org/jira/browse/HDDS-7105) PR #[3662](https://github.com/apache/ozone/pull/3662)] Introduce an interface `OMHashCodeGenerator` which translates each of the `OBJECT_STORE "OBS"` bucket layout key path names into a hash code based on the corresponding hash function used.
The write operations on different key paths now have their corresponding hash codes and are allotted a thread writer (executor) index for execution determined via the modulo (`hashCode % om.num.concurrent.write.threads`) - this enables concurrency for write operations.
Please refer [link](https://issues.apache.org/jira/secure/attachment/13047873/HDDS%20-%20Allow%20Concurrent%20Writers%20in%20OM%20for%20OBS%20Bucket%20Key%20Paths_8Aug2022.pdf).
