[jira] [Closed] (UIMA-4265) Add warmup option to a UIMA-AS service
instance
[ https://issues.apache.org/jira/browse/UIMA-4265?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.

> URL: https://issues.apache.org/jira/browse/UIMA-4265
> Project: UIMA
> Issue Type: New Feature
> Components: Async Scaleout

>
> 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.
