Re: [infinispan-dev] Infinispan embedded off-heap cache

Thanks Peter. The plan is for Dmitry and I to at first extend VanillaSharedHashMap and groom it into an ISPN7 join via their DataContainer API bridge.

That ExtendedVSHM will be morphed into a fully inter-operable JCACHE operand will - initially be brokered by the ISPN 7 config (JSR107 <----> VSHMExtendedDataContainer <----> VSHM) - eventually, possibly, be rendered with ExtendedVSHM directly implementing javax.cache.Cache (in addititon to DataContainer) On 03/07/2014 11:43 AM, Peter Lawrey wrote: > In the medium term I would see SHM supporting a DataContainer.
