hlteoh37 opened a new pull request, #20244:
URL: https://github.com/apache/flink/pull/20244
… for AsyncSinkWriter
## What is the purpose of the change
This pull request makes the RateLimitingStrategy used in AsyncSinkWriter
configurable by the sink implementer. That way a sink implementer can decide to
implement a custom RateLimitingStrategy.
## Brief change log
- Introduced RateLimitingStrategy interface
- Implemented a CongestionControlRateLimitingStrategy
- Migrated tracking of inFlightMessages from AsyncSinkWriter into the
RateLimitingStrategy
- Introduced logic within AsyncSinkWriter to check with RateLimitingStrategy
if the next request should be blocked.
- Introduced a new AsyncSinkWriter constructor and deprecated the old
AsyncSinkWriter constructors.
## Verifying this change
This change added tests and can be verified as follows:
- Added test that verifies AsyncSinkWriter respects the RateLimitingStrategy
passed into the constructor
- Added test that verifies AIMDRateLimitingStrategy follows a linear
increase and multiplicative decrease
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): no
- The public API, i.e., is any changed class annotated with
`@Public(Evolving)`: yes
- The serializers: no
- The runtime per-record code paths (performance sensitive): no
- Anything that affects deployment or recovery: JobManager (and its
components), Checkpointing, Kubernetes/Yarn, ZooKeeper: no
- The S3 file system connector: no
## Documentation
- Does this pull request introduce a new feature? yes
