I would like to be able to pass runtime parameters from my main application to
distributed AEs. Some parameters might be one-time overrides while others may
be per-CAS. I'm not sure if using a Feature Structure is the right approach.
For example, the pipeline may have a database connection string parameter, and
the user will be asked for the username and password to use along the way.
Passing these parameters as FS with each CAS would guarantee that any
distributed AE would see them, but passwords sent this way may be exposed via a
CAS/XMI writer. Other parameters, such as a run mode for the pipeline (debug,
logging level, dump intermediate results, etc.) are also candidates for
distributing from the main pipeline controller (e.g., SimpleRunCPE) to remote
AEs.
Besides the FS collection is there another mechanism for distributing
parameters? I've read enough to know that extending the DocumentAnnotation is
not recommended for JCas.
Thanks!
Chuck
