             Summary: OffHeap Data Container
                 Key: ISPN-6866
                 URL: https://issues.jboss.org/browse/ISPN-6866
             Project: Infinispan
          Issue Type: Feature Request
          Components: Core
            Reporter: Tristan Tarrant
            Assignee: William Burns
             Fix For: 9.0.0.Final


We want to be able to allocate data off-heap.
Requirements / ideas:
* data should be stored in Direct ByteBuffers, or easily accessible as such so that integration with other types of I/O (clustering, persistence, server) can be done efficiently
* consider both raw  byte[] storage (such as that performed by servers) and store as binary
* allocator should be pluggable
* out-of-the-box implementation should use Netty Buffers
* type of allocation (heap or off-heap) should be per-cache
* off-heap allocation configuration should be global (per-container) or possibly shared among multiple containers
* optional off-heap allocation for keys
* ability to monitor both global and per-cache memory usage
