----------------------------------
Summary: Need an undeprecated Reshuffle transform
Key: BEAM-4372
URL: https://issues.apache.org/jira/browse/BEAM-4372
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Reporter: Raghu Angadi
Assignee: Kenneth Knowles
{{Reshuffle}} transform is a convenient wrapper around GBK. It preserves user
windowing correctly which is not always obvious for users. It usage has grown
over many months since it was deprecated as it makes it easier for potential
incorrect/unportable use of GroupByKey semantics. See [dev
thread|https://lists.apache.org/thread.html/820064a81c86a6d44f21f0d6c68ea3f46cec151e5e1a0b52eeed3fbf@%3Cdev.beam.apache.org%3E]
for more discussion.
There is a broad agreement we do need a transform that is meant for its common
used purpose in user pipeline : to control parallelism (e.g. to control
connections to a DB).
