Add tooling to measure things for tuning space/time
---------------------------------------------------
Key: UIMA-1090
URL: https://issues.apache.org/jira/browse/UIMA-1090
Project: UIMA
Issue Type: Improvement
Components: Core Java Framework
Affects Versions: 2.2.2
Reporter: Marshall Schor
Priority: Minor
Some fairly simple tooling could help users discover easy things to do to tune
their UIMA application. One such tool might measure the % of space in the CAS
used by unused features. This might occur when using a general component that
could set many feature fields, but intentionally running it in a mode where
many of the fields are unused. In this case, changing the type definition to
exclude those fields would save space in the CAS, which could be significant in
those cases where a lot of instances of those types are created (e.g., tokens).
Such a tool could be packaged as a JMX measurement, or as a special annotator,
or as some new part of the framework.
