Reload updated resources while an analysis pipeline is running
--------------------------------------------------------------
Key: UIMA-1970
URL: https://issues.apache.org/jira/browse/UIMA-1970
Project: UIMA
Issue Type: New Feature
Components: Core Java Framework
Affects Versions: 2.3.1SDK
Reporter: Jörn Kottmann
In many use cases resources used by Analysis Engine are updated more frequently
than the AE implementation.
Samples of such resources are huge dictionaries which are extended with new
names on a daily basis
or statistical models which are re-trained frequently to be adjusted to data
from the past minutes.
For a resource updates an analysis pipeline has to be stopped and started
manually to pick up the updated resource.
It would be nice if the framework could automate this procedure. In order to do
that it must have a capability to detect
updated resources and perform the re-initialization of affected Analysis
Engines.
If the pipelines run multiple instances of these Analysis Engines it would be
nice if a rolling
update could be performed in a way that the processing of CASes never comes to
an halt.
That should be handled in different issues for the CPE and UIMA-AS.
