---------------------------------------
Summary: Reduce resource consumption during component checks
Key: FELIX-6399
URL: https://issues.apache.org/jira/browse/FELIX-6399
Project: Felix
Issue Type: Improvement
Components: System Ready
Affects Versions: systemready-0.4.2
Reporter: Carsten Ziegeler
Fix For: systemready-0.4.3
the components readycheck is each time (every 5 secs) iteration over all DS
components just to check for a few. The iteration includes access to the
service registry which (in Felix framework 6.x) has a lock
There are two optimizations:
- components check should only check for the configured ones instead of
iterating over all components just to find the ones interested in
- the resultcan be cached until an event occurs (service changed event of the
SCR runtime as the runtime has a change count property to exactly avoid polling)
