Ben Cotton commented on ISPN-871:
---------------------------------
Was this ever done?
If so, is it documented how to configure an off-heap Cache in a specific ISPN version?
If not, I would recommend the consideration of Peter Lawrey's OpenHFT Chronocle
net.openhft.collections.HugeHashMap implementation ... which is based on a off-heap
MappedByteBuffer onto any/all of (/dev/shm, tmpfs, ext4) and is exceedingly high
performant.

Out-of-heap data container implementation

Project: Infinispan
Issue Type: Feature Request
Components: Configuration
Reporter: Manik Surtani
Assignee: Tristan Tarrant
Labels: gc, jni, native, performance, research
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.
