Jay Patel created CASSANDRA-7883: ------------------------------------ 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
