------------------------------------
Summary: Allow plugging JEMalloc for off-heap memtables
Key: CASSANDRA-7883
URL: https://issues.apache.org/jira/browse/CASSANDRA-7883
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Jay Patel
Fix For: 2.1.1
Off-heap memtables (memtable_allocation_type:offheap_objects) introduced by
CASSANDRA-6694 uses native GCC allocator. Provide an option to use JEMalloc
allocator (http://www.canonware.com/jemalloc/) which is good to reduce
fragmentation.
CASSANDRA-3997 adds below option for off-heap caches and metadata. But it's not
in effect for off-heap memtables. Should be use the same option or add another?
memory_allocator: JEMallocAllocator
