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

Hi,

We want to get started w a POC build of doing this using Peter Lawreys HugeHashMap solution (details of the POC build ambition = http://infinispan-developer-list.980875.n3.nabble.com/infinispan-dev-Infinispan-embedded-off-heap-cache-td4026102.html). Any success (of course) to be immediately contributed back for ISPN's consideration to use.

ROAD-BLOCK:   Can't build! How do you build ISPN 7 from GIT?  Tryng this:

Assuming all I need is JDK 1.7 anf Maven 3

1.  Fork https://github.com/infinispan/infinispan/ to my GIT repo
2.  Clone from my GIT repo's ISPN origin to my desktop workspace
3. cd to the infinispan root pom.xml directory
4.  Build from my workspace = `mvn clean compile`

#this is the ROADBLOCK point - how do we resolve the below unresolved ' infinispan-extended-statistics'?


See ben at 52-b.liq,risk.ny.jpm.com> mvn clean compile

> 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.
