[jira] [Commented] (CONFIGURATION-530) AbstractFileConfiguration.getProperty(String key) locking causes thread halt

["Oliver Heger (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CONFIGURATION-530?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13604703#comment-13604703 ] 

Oliver Heger commented on CONFIGURATION-530:
--------------------------------------------

Version 2 will not be backwards compatible, there are some major design changes.

AFAICT, there is currently no interest in working on the 1.x branch. Also, I am not sure whether the problems related to relading can be changed with reasonable effort and without breaking existing applications.

> 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?).
