All Implemented Interfaces:

AutoCloseable, org.rocksdb.WriteBatchInterface

public class ZbWriteBatch
extends org.rocksdb.WriteBatch

Extension to WriteBatch to expose a few protected methods that allow us to reuse buffers more easily.

NOTE: all methods that use DirectBuffer types explicitly read from the underlying byte array starting at offset 0. This is a limitation of RocksDB which unfortunately doesn't provide any native methods that use offset for those buffers yet.
