--------------------------------
Summary: Handle WindowInto transforms in portable Flink runner
directly
Key: BEAM-4128
URL: https://issues.apache.org/jira/browse/BEAM-4128
Project: Beam
Issue Type: New Feature
Components: runner-flink
Reporter: Ben Sidhom
Assignee: Aljoscha Krettek
This is mostly an optimization, but by having the runner itself handle
well-known WindowFns (e.g., global windowing, fixed windowing), we can avoid
round trips to the SDK harness. This requires some pipeline surgery
pre-translation if we want it to work efficiently in conjunction with fusion.
