[infinispan-issues] [JBoss JIRA] (ISPN-11176) XSite Max Idle

Will Burns created ISPN-11176: --------------------------------- Summary: XSite Max Idle Key: ISPN-11176 URL: https://issues.redhat.com/browse/ISPN-11176 Project: Infinispan Issue Type: Enhancement Components: Cross-Site Replication, Expiration Reporter: Will Burns Fix For: 11.0.0.Final Max idle expiration currently doesn't work with xsite. That is if an entry was written and replicated to both sites but one site never reads the value, but the other does. If they then need to read the value from the other site it will be expired (assuming the max idle time has elapsed). There are a few ways we can do this. 1. Keep access times local to every site. When a site finds an entry is expired it asks the other site(s) if it has a more recent access. If a site is known to have gone down we should touch all entries, since they may not have updated access times. Requires very little additional xsite communication. 2. Batch touch commands and only send every so often. Has window of loss, but should be small. Requires more site usage. Wouldn't work for really low max idle times as an entry could expire before the touch command is replicated. -- This message was sent by Atlassian Jira (v7.13.8#713008)
