[infinispan-issues] [JBoss JIRA] Commented: (ISPN-858) MIMECacheEntry requires a version

Galder Zamarreño commented on ISPN-858:
---------------------------------------

Yeah, reached the same conclusion in JBPAPP-5715. I was thinking of using along the lines of the version use in HotRod/Memcached, which integrates cluster node information if available, and an counter. Why would relying on a counter lead to unnecessary cache invalidation? I'd imagine that the counter would get updated whenever the new MIMECacheEntry gets updated which happens on a put() call

I can only think of too much invalidation happening if the counter was incremented in spite of the contents not changing.

> ETag calculation requires MIMECacheEntry to carry a version similar to HotRod/Memcached in order to avoid collisions with closely followed updates.
