Key: CASSJAVA-91
URL: https://issues.apache.org/jira/browse/CASSJAVA-91
Project: Apache Cassandra Java driver

There are many places where Cassandra uses offheap memory and several methods
to do it, it would be nice to have a summary doc about this usage.
A draft version:
||Case||Off-heap memory type||Way to monitor||Related configuration||
|offheap_buffers memtables|Direct buffer| | |
|offheap_object memtables|Native allocator| | |
|Chunk cache| | | |
|Hints| | | |
|Repair Merkle trees| | | |
|Bloom filters|Native allocator| | |
|Index summaries|Native allocator| | |
|Compression metadata|Native allocator| | |
|Direct IO commitlog | | | |
|Compression| | | |
|Netty PooledByteBufAllocator|Unsafe.allocateMemory| | |
