---------------------------------------
Summary: More efficient memory handling for tiny off-heap cache
entries
Key: CASSANDRA-9929
URL: https://issues.apache.org/jira/browse/CASSANDRA-9929
Project: Cassandra
Issue Type: Improvement
Reporter: Robert Stupp
Assignee: Robert Stupp
Priority: Minor
Fix For: 3.x
CASSANDRA-9738 + CASSANDRA-9739 usually have tiny cache entries. The overhead
of any general-purpose memory allocator is probably too high.
[~benedict] proposed a chunked allocation strategy for OHC that allows to
allocate the whole memory up-front - thus reducing the malloc/free overhead to
0.
