------------------------------------
Rather than using a standard hashmap in C, what about the concurrent hashmap from TBB?
Out-of-heap data container implementation
-----------------------------------------
Key: ISPN-871
URL:
https://issues.jboss.org/browse/ISPN-871
Project: Infinispan
Issue Type: Feature Request
Components: Configuration
Reporter: Manik Surtani
Assignee: Alban Seurat
Labels: gc, jni, native, performance, research
Fix For: 5.2.0.Alpha4, 5.2.0.Final
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.
