Alban Seurat commented on ISPN-871:
-----------------------------------

mmap-container module has been properly added to the project Infinispan, it's building the shared object using GNU toolchain driven by maven. Next phase is to allow to seamlessly integrate it into a Java using JNA

> The DataContainer interface could be implemented using a off-heap impl in C, using mmap.  It would require custom memory management (gc-lite?) to reclaim free space, as well as reimplementing of eviction algorithms to maintain the contract of a self-sizing data container, but the benefits of this would be the ability to address very large amounts of memory with minimal gc overhead from the JVM.
