Joern Kottmann commented on OPENNLP-261:
----------------------------------------
Usually I implement an Analysis Engine to read from a data base and pass it a
CAS with an Id as input. This way it can retrieve the content and place it in a
new CAS view. And a second one to write back, I am not sure why it would be an
advantage to put both in one AE, you would still need to configure it in some
way to indicate if it should read or write.
This approach also works nicely with UIMA-AS because then every worker server
connects directly to the data base, and there is no bottleneck, if everything
goes through the ActiveMQ broker it can be challenging to give it enough
bandwidth.
