Fix Version/s: (was: 2.3S)
2.3AS
> Client of a CAS Multiplier should be able to stop processing of a CAS
> ---------------------------------------------------------------------

> Key: UIMA-1391
> URL: https://issues.apache.org/jira/browse/UIMA-1391
> Project: UIMA
> Issue Type: Improvement
> Components: Async Scaleout
> Reporter: Burn Lewis
> Assignee: Jerry Cwiklik
> Fix For: 2.3AS
>
>
> Normally the number of CASes generated by a Cas Multiplier is determined by
> the CM itself, but with an aggregate CM that number may be hard to anticipate
> or control. Some applications may not need all of the generated CASes ...
> they may be satisfied once an appropriate amount of information has been
> returned.
> Hence it would be convenient for the client to be able to request that the CM
> stop generating CASes, and if an aggregate, stop processing any internal
> CASes generated from the input CAS. Such a request is probably only useful
> for CMs acting as pure segmenters ... if the CM is merging CASes or
> resegmenting them then the process could be terminated by the application
> upon receiving an end-of-stream CAS. It might be an acceptable
> simplification to have the stop request stop all processing of active CASes,
> but then again it may be easily handled by the changes being made to stop an
> aggregate CM when a generated CAS produces an exception.
