Re: [infinispan-dev] FIFO ordering...

My solution is per node at this point. For what I need that is enough but I don't feel it's a complete solution. Other grid applications I've used like this support it per node as well but distribute the call once the initial cache node is emptied. This can lead to starvation but it's easy. I can't say I like it. I would think we could come up with something better if needed. Yes, I looked at FIFODataContainer. In fact my initial implementation was to create a new data container that kept a queue and returned an ordered keyset(). I'd like to add queue support regardless of DataContainer but there doesn't seem to be a way at that low of a level to hook into things across data container impl.

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?
