Ben Cotton commented on ISPN-871:
---------------------------------

All build issues are now resolved (we were trying to build within a bank's firewall, which is perfectly futile).

It is our understandng that there will a OpenHFT HC Alpha Release in Maven Central next weekend. At that time, Dmitry and I will take the OpenHFT dependency tag and proceed to build a branch of Red Hat's ISPN 7 that will treat net.openhft.collections.SharedHashMap as a Red Hat Infinispan 7 default impl of javax.cache.Cache

A diagram of this build effort can be found here: https://raw.github.com/Cotton-Ben/OpenHFT/master/doc/AdaptingOpenHFT-SHM-as-JCACHE-Impl.jpg

Also the OpenHFT view of his effort will be tracked here: https://github.com/OpenHFT/HugeCollections/issues/13

> The {{DataContainer}} interface could be implemented using a off-heap impl in C, using a wrapper around [TBB|http://threadingbuildingblocks.org/]'s concurrent hashmap.
> Cheap and easy way, no memory management needed, at worst case same performance as the Java CHM-like impl of the data container + some JNI overhead.  Potential benefit of large data heaps.
