Work Description: nehsyc opened a new pull request #12578:
URL: https://github.com/apache/beam/pull/12578
This is to support GroupIntoBatches transform with runner determined sharding in Dataflow. To mitigate the limited parallelism introduced by an implicit grouping on keys, we allow the states/timers associated with each input key to be shardable.
This PR modifies the state and work caching in the Dataflow Java runner such that the states of different shards of keys are tracked separately, to prepare it for shardable GroupIntoBatches.
See more details in https://s.apache.org/sharded-group-into-batches.
