Fields

Modifier and Type	Field and Description
protected static com.fasterxml.storemate.shared.util.BufferRecycler	_bufferRecycler We can reuse read buffers as they are somewhat costly to allocate, reallocate all the time.
protected EntryKeyConverter<K>	_keyConverter
protected com.fasterxml.jackson.databind.ObjectMapper	_mapper
protected RequestPathStrategy<?>	_pathFinder
protected ClusterServerNode	_server
protected static int	CHUNK_SIZE Not sure what is optimal chunk size, but 16k sounds like a reasonable starting point.
