[Dan Berindei (Jira)]

    [ https://issues.jboss.org/browse/ISPN-7912?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13730094#comment-13730094 ] 

Dan Berindei commented on ISPN-7912:
------------------------------------

Maybe we wouldn't need a queue if we could write to the expiration DB directly, without merging with the existing list of values?

We may be able to do that if if we changed the format of the expiration "table" to {{key = <expiration timestamp> + <key bytes>, value = <nothing>}}.

> Currently you can only insert 10000 elements into the rocks db store until you will block a thread until the expiration reaper is ran. Instead we should offer elements to the queue and upon failure utilise the persistence executors to run purge.
