[infinispan-issues] [JBoss JIRA] (ISPN-3834) New advanced indexing flag to skip deletion of previous entry

[Adrian Nistor (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-3834?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12932323#comment-12932323 ] 

Adrian Nistor commented on ISPN-3834:
-------------------------------------

Efficiently and reliably detecting the presence of a previous value is crucial also for ISPN-3795, not just for this perf improvement. I would ponder this a bit more before adding a new _unsafe_ flag.

> I'm needing to add a org.infinispan.context.Flag.SKIP_INDEX_CLEANUP which does not issue an UPDATE index command but a simple ADD.
> Just ADD is way more efficient, just we can't automatically detect it safely so I need a flag to allow for efficient data import.
