[infinispan-issues] [JBoss JIRA] (ISPN-3617) Inconsistent L1 in non-tx distributed cache

[William Burns (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-3617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12823691#comment-12823691 ] 

William Burns commented on ISPN-3617:
-------------------------------------

Actually I think this is related to ISPN-3273.  I have a guess as to what you may have seen.

My guess is that this operation happened:

# put ran on primary owner
# primary owner replicates to backup owner (not yet committed on primary) - backup owner invalidated on non owner
# get from non owner retrieves the old value from owner
# primary owner completes but doesn't invalidate the non owner since it was the one who updated

I will have to write up a test, but I am pretty sure this is what you saw.

> When the change is replicated to backup owner, it sends the InvalidateL1Command to backup owners before committing the entry in EntryWrappingInterceptor (it performs the WriteCommand in parallel with sending the invalidation commmand, but then it waits until the invalidation request gets acked. If a GET is executed between the invalidation and committing the entry, the response contains outdated result and the L1 will not be invalidated until next write operation.
