Processing order of parent CAS different on UIMA and UIMA AS
------------------------------------------------------------
Key: UIMA-1245
URL: https://issues.apache.org/jira/browse/UIMA-1245
Project: UIMA
Issue Type: Bug
Components: Async Scaleout
Reporter: Eddie Epstein
Arron Kaplan raised the question of when parent CASes are processed relative to
their children. See http://markmail.org/message/5cop7iv2nshouhgs As of now,
the processing order for a multi-threaded UIMA AS aggregate is different than
that for a single-threaded UIMA aggregate.
A discussion with Burn, Adam, Jerry, Marshall and myself concluded that the
default processing order for UIMA AS should be changed to be the same as in
UIMA, in order to have the same application behavior for both. This will be
done by suspending flow of a parent CAS after it is returned from a
CasMultiplier delegate until all its children CASes have finished processing.
However, there also needs to be a UIMA AS deployment option for CasMultiplier
delegates that allows the parent CAS to resume processing immediately after
being returned from the CM. This option is needed to enable parallel processing.
