Andy Xu created BEAM-1408:
-----------------------------
Summary: outputWithTimestamp() accepts timestamps that will fail
preconditions
Key: BEAM-1408
URL: https://issues.apache.org/jira/browse/BEAM-1408
Project: Beam
Issue Type: Improvement
Components: sdk-java-core
Reporter: Andy Xu
Assignee: Davor Bonaci
Priority: Minor
We have accidentally created events with *wrong* timestamps in the future which
are accepted by
outputWithTimestamp(), but will fail at a later step:
java.lang.IllegalStateException: Timer 472976-06-15T20:09:57.269Z is beyond
end-of-time
atcom.google.cloud.dataflow.sdk.repackaged.com.google.common.base.Preconditions.checkState(Preconditions.java:199)
at
com.google.cloud.dataflow.sdk.util.ReduceFnRunner.scheduleEndOfWindowOrGarbageCollectionTimer(ReduceFnRunner.java:1050)
[...]
Would it make sense to implement a check already at outputWithTimestamp() level
to fail early?
