[GitHub] [beam] rvballada opened a new pull request #15464: [BEAM-12634] JmsIO auto scaling feature
rvballada opened a new pull request #15464:
URL: https://github.com/apache/beam/pull/15464
Add autoscaling feature to JmsIO connector:
- Provide a generic AutoScaler interface with the ability to implement getTotalbacklogBytes or/and getSplitBacklogBytes,
- Provide a DefaultAutoScaler implementation (returning BACKLOG_UNKNWOWN in both case),
- add a new withAutoScaler configuration method to inject a custom auto scaler
- https://issues.apache.org/jira/browse/BEAM-12634
