[infinispan-issues] [JBoss JIRA] (ISPN-5607) NearCache: it is possible to read stale data with a put/remove followed by a get

Enrico Olivelli updated ISPN-5607:
----------------------------------
Steps to Reproduce:
It cannot be reproduced systematically, but the steps are "simple":
- write an value, value=A
- write an value, value=B
- issue a get on the entry, it could return value=A in case of high network load (or slow
network connection)
it is simpler to reproduce while using a network of 2-3 servers, when the entry is hosted
not on the same server that the listener is attechad to

Key: ISPN-5607
URL: https://issues.jboss.org/browse/ISPN-5607
Project: Infinispan
Issue Type: Bug
Components: Core
Affects Versions: 7.2.3.Final
Environment: one hotrod client with 2 hotrod servers
Reporter: Enrico Olivelli
Priority: Blocker
Wites to the NearCache do not invalidate/update local data on put/remove operations, and
so the NearCache (LAZY MODE) is invalidated using an eventlistener in an asynch way.
It is possible for a client to write a value and issue a get on the same key, and the
result of the get would not be the latest value but the one which was present before the
update operation.
This happens frequently when there is very much traffic on the connection of the listener
which receives the events for the NearCache.
It would be better at least to invalidate locally every entry modified from the client
itself
