Siyuan Chen updated BEAM-10475:
-------------------------------
Description:
[https://s.apache.org/sharded-group-into-batches|https://s.apache.org/sharded-group-into-batches__]
Improve the existing Beam transform, GroupIntoBatches, to allow Dataflow runner
to choose different sharding strategies depending on how the data needs to be
grouped. The goal is to help with the situation where the elements to process
need to be co-located to reduce the overhead that would otherwise be incurred
per element, while not losing the ability to scale the parallelism. The
essential idea is to build a stateful DoFn with shardable states.
