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.Beta1, 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
