Oliver Heger commented on CONFIGURATION-530:
--------------------------------------------
There is still a lot to do before version 2.0 is ready. There is no planned
release date yet (here in Commons we do not have fix release schedules).
> AbstractFileConfiguration.getProperty(String key) locking causes thread halt
> ----------------------------------------------------------------------------
>
> Key: CONFIGURATION-530
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-530
> Project: Commons Configuration
> Issue Type: Bug
> Components: File reloading
> Affects Versions: 1.9
> Reporter: yair ogen
> Priority: Critical
>
> Every call to getProperty causes a lock (related to the reload
> functionality). In a near real-time system where we have many concurrent
> threads this affects heavily on the application TPS.
> Possible solution will be: getProperty only returns current value. Reload
> when needed occurs in a background thread that updates the in-memory map
> (perhaps by using CopyOnWrite collections?).
