---------------------------------
Summary: Allow combiner lifting with AfterProcessingTime trigger
in Dataflow Runner
Key: BEAM-4525
URL: https://issues.apache.org/jira/browse/BEAM-4525
Project: Beam
Issue Type: Bug
Components: runner-dataflow
Reporter: Sam Whittle
Assignee: Sam Whittle
This seems safe with AfterProcessingTime since otherwise assigning to panes is
based upon system timing. A valid output without combiner lifting would be for
all the elements to arrive in a single batch with the same timestamp so
allowing combiner lifting seems equivalent and more efficient.
