Jerry Cwiklik closed UIMA-4265.
-------------------------------
Resolution: Fixed
When enabled via -DWarmUpDataPath=<PATH>, the new code will read CASes from a
zip file pointed to by PATH to prime AE pipeline. Both sync and async pipelines
are supported for the priming.
> Add warmup option to a UIMA-AS service instance

> Key: UIMA-4265
> URL: https://issues.apache.org/jira/browse/UIMA-4265
> Project: UIMA
> Issue Type: New Feature
> Components: Async Scaleout
> Reporter: Eddie Epstein
> Assignee: Jerry Cwiklik
> Fix For: 2.6.1AS
>
>
> A UIMA-AS service capacity can be dynamically expanded by starting new
> instances to share the load. However, some analytics require a warm-up period
> to achieve desired latency; in this case adding a cold service instance to a
> collection of warm instances can temporarily degrade service performance.
> The request here is to add a warm-up option to UIMA-AS service startup.
> Warm-up CASes should be specified as a zipfile containing multiple CASes in
> either compressed XmiCas or binary compressed CAS formats, or a directory
> containing these zipfiles. The CASes would be run after the service annotator
> has initialized but before it registers as listener on the service input
> queue.
