I posted JIRA issue https://jira.jboss.org/jira/browse/ISPN-132 a

I've worked on this internally and have a working solution but I'd
like to know it's coming soon or not. If not I will continue
working on it but I need some guidance on the design to make sure it
fits properly into Infifispan.
Hmm, almost as a side effect of an ordered data container (needed for
eviction), you would have a FIFO queue, albeit one that just gives you
a view of state local to the node. The DataContainer impl used when
you enable FIFO eviction is the FIFODataContainer, and calling
Cache.keySet().iterator() would iterate over the FIFODataContainer.
Does your solution actually provide a global view in a FIFO manner?
And if so, how does it provide FIFO guarantees over concurrent
insertions made on different cluster nodes? Or is this a non-strict
FIFO impl?
Cheers
