> Timeout needs different implementation to eliminate interaction with CAS pool
> size

> Key: UIMA-1133

> Project: UIMA
> Issue Type: Improvement
> Components: Async Scaleout
> Reporter: Eddie Epstein
> Assignee: Jerry Cwiklik
>
> When a timeout value is specified for process calls, a timer is set for each
> processCas request. If an aggregate controller (or client API) sends multiple
> process requests to the same service, the timeout must be increased to
> account for the potential processing delay of the earlier requests. Currently
> the timeout value is static, specified in the deployment descriptor; if a
> user changes the CAS pools size, they may have to change the timeout to
> compensate.
> A better design would decouple these things by changing the implementation of
> timeout. For example, the timeout value could be dynamic, taking into account
> the number of outstanding requests sent by the same client. The new
> implementation should take into account the need to set appropriate
> time-to-live values for the request messages.
