### Motivation This is the final part of PIP-74. https://github.com/apache/pulsar/wiki/PIP-74%3A-Pulsar-client-memory-limits ### Modifications 1. This feature does not take effect by default for now. Consumer memory usage take account only if `autoScaledReceiverQueueSizeEnabled` is enabled. We can change this to default when this feature is verified by more production usage. 2. Block consumer receiver queue size expansion if memory usage > 75% 3. Trigger consumer receiver queue size shrinking if memory usage > 95% ### Verifying this change - [ ] Make sure that the change passes the CI checks. *(Please pick either of the following options)* This change added tests and can be verified as follows: - ConsumerMemoryLimitTest - MemoryLimitControllerTest ### Does this pull request potentially affect one of the following parts: *If `yes` was chosen, please highlight the changes* - Dependencies (does it add or upgrade a dependency): (no) - The public API: (no) - The schema: (no) - The default values of configurations: (no) - The wire protocol: (no) - The rest endpoints: (no) - The admin cli options: (no) - Anything that affects deployment: (no) ### Documentation Check the box below and label this PR (if you have committer privilege).
