Vinci Services have getMetaData timeout problems when there are a large number
of clients
-----------------------------------------------------------------------------------------
Key: UIMA-821
URL: https://issues.apache.org/jira/browse/UIMA-821
Project: UIMA
Issue Type: Bug
Components: Transport Adapters - SOAP, Vinci
Affects Versions: 2.2.1
Reporter: Adam Lally
Assignee: Adam Lally
Fix For: 2.2.2
When I have a large number of clients I am experiencing timeouts in the
getMetadata call. There's currently no way to configure this timeout - in
issue UIMA-33, we made the client descriptor's <timeout> element apply only to
the process call, so getMetadata defaults to a 1 minute timeout. With a small
number of clients this is OK, but the Vinci service has a default thread pool
of size 20 (also not configurable through the UIMA descriptor), so if you have
more clients than this then this pool may get filled up with process requests
forcing a getMetadata call to wait much longer. Probably both of these
settings should be configurable.
