Classes in org.apache.cassandra.utils.memory used by org.apache.cassandra.db
Class	Description
ByteBufferCloner	Cloner class that can be use to clone partition elements using on-heap or off-heap buffers.
NativeAllocator	This NativeAllocator uses global slab allocation strategy with slab size that scales exponentially from 8KiB to 1MiB to serve allocation of up to 128KiB.

Class	Description
MemtableAllocator
MemtableCleaner	The cleaner is used by `MemtableCleanerThread` in order to reclaim space from memtables, normally by flushing the largest memtable.
MemtablePool	Represents an amount of memory used for a given purpose, that can be allocated to specific tasks through child MemtableAllocator objects.

MemtableAllocator
MemtableAllocator.SubAllocator	Mark the BB as unused, permitting it to be reclaimed
MemtableBufferAllocator
MemtableCleaner	The cleaner is used by `MemtableCleanerThread` in order to reclaim space from memtables, normally by flushing the largest memtable.
MemtablePool	Represents an amount of memory used for a given purpose, that can be allocated to specific tasks through child MemtableAllocator objects.
MemtablePool.SubPool	Note the difference between acquire() and allocate(); allocate() makes more resources available to all owners, and acquire() makes shared resources unavailable but still recorded.
NativeAllocator	This NativeAllocator uses global slab allocation strategy with slab size that scales exponentially from 8KiB to 1MiB to serve allocation of up to 128KiB.
