Work Description: je-ik commented on issue #9841: [BEAM-8439] enable
empty bundles in ParDoLifecycleTest
URL: https://github.com/apache/beam/pull/9841#issuecomment-544408386
R: @mxm
This could be the proper fix. But please validate my logic:
- because `checkInvokeStartBundle` is called in
`DoFnOperator.processWatermark1`, it is possible that `startBundle` gets
invoked even though there are no actual elements flowing into the operator
(e.g. higher parallelism than the actual number of elements). Therefore, the
sequence of calls of the lifecycle methods is `startBundle` -> `finishBundle`
with no intermediate `processElement`. It should be therefore captured in the
test directly.
