### What needs to happen? Current version of KinesisIO EFO consumer can not adapt to data skew in Kinesis shards. Moreover, when consuming from a stream which experiences often re-sharding, some runner workers may end up having 0 subscriptions. Non-EFO consumer has implementation of `getSplitBacklogBytes()` which runners can use for dynamic scaling: https://github.com/apache/beam/blob/cd0f44b3751c9d4b583b2a3e2e1d10aeb75695b9/sdks/java/io/amazon-web-services2/src/main/java/org/apache/beam/sdk/io/aws2/kinesis/KinesisReader.java#L161 `EFOKinesisReader` should implement a similar mechanism, too: https://github.com/apache/beam/blob/cd0f44b3751c9d4b583b2a3e2e1d10aeb75695b9/sdks/java/io/amazon-web-services2/src/main/java/org/apache/beam/sdk/io/aws2/kinesis/EFOKinesisReader.java#L31 ### Issue Priority Priority: 3 (nice-to-have improvement) ### Issue Components - [ ] Component: Python SDK - [X] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [X] Component: IO connector - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
