Not sure I fully understand your problem. In the CPE, the CR runs in its own thread supplying CASes to processing pipelines. Cas Consumer(s) run in a dedicated thread(s) as well. The processingUnitThreadCount property determines scaleout for your AEs if you set it to say 3, you get 3 processing threads (pipelines) and 3 instances of each AE.
Take a look at this document: http://uima.apache.org/d/uimaj-2.3.1/tutorials_and_users_guides.pdf page 61. Can you explain this better: "...this does not work because it only adds the 3 "levels" reading, analyzing, writing to differnt threads." - Jerry On Wed, Nov 7, 2012 at 11:09 AM, Andreas Niekler < aniek...@informatik.uni-leipzig.de> wrote: > Hi there, > > i have a uima defininition including a Reader, The Analysis chain and a > consumer.
