public class TBinaryProtocol
extends org.apache.thrift.protocol.TBinaryProtocol

Thrift original TBinaryProtocol implementation relies on the fact that all TTransport instances are byte array backed, so for all it's operations they can just use that array, requesting it using TTransport.getBuffer(). Disruptor implementation follows different approach, it uses direct byte buffers (backed by native memory, allocated by Unsafe) which allows it to free/reallocate memory when needed and doesn't bloat JVM Heap, as there is no guarantee that all of the data would "die young" and put no pressure on Garbage Collector.
