[jboss-jira] [JBoss JIRA] (JGRP-1551) AgePutCache: use 1 timer tasks for all elements rather than 1 task per element

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/JGRP-1551?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12740359#comment-12740359 ] 

Bela Ban commented on JGRP-1551:
--------------------------------

Actually, I didn't modify AgeOutCache, but created a new ExpiryCache which does *not* use any timer tasks. TP uses it as the new who-has cache, replacing AgeOutCache.

> Currently, AgeOutCache uses 1 task for every element. Change this to 1 task for all elements, so we reduce the number of tasks in the timer.
> AgeOutCache is used e.g. in TP, to see if we've recently requested fetching of a physical address from the discovery protocol, to suppress too many discovery requests.
> The task would be started whenever add() is called and a task is not yet already running. After all elements have expired, the task would terminated until the next add() is called.
