Subject [jira] [Updated] (IGNITE-3164) Add an option to send resulting value instead of entry processor in transactional cache
Date Wed, 18 May 2016 11:47:12 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-3164?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Valentin Kulichenko updated IGNITE-3164:
----------------------------------------
    Description: 
In some cases user can't guarantee that EP behaves consistently on all nodes. In transactional
cache this can lead to inconsistent cache, because we invoke EP on both primary and backup
nodes.

We can add {{withSendValueToBackup()}} flag (naming is arguable) which will override current
default behavior.

We also need to update documentation, especially provide the explanation of EP behavior in
atomic and transactional caches.
