---------------------------------
Summary: Make sure we unit test bounded sessions
Key: BEAM-279
URL: https://issues.apache.org/jira/browse/BEAM-279
Project: Beam
Issue Type: Bug
Reporter: Mark Shields
A few customers have been using Window.into(Sessions...) and of course quickly
realize they are exposed to unbounded sessions.
We should have unit tests to confirm various combinations of
AfterPane.elementCountAtLeast and AfterProcessingTime... correctly force
sessions to be broken apart.
We should also check this all works with repeated messages with the same
timestamp (since they will create the exact same session window and can thus
see trigger state from previous sessions).
At some point we may may flow into reworking bounded sessions to be done
directly rather than via Sessions plus triggers.
