> I've found a way to make better use of direct buffer access in the Compact Protocol that makes reading varints faster. When there's at least 5 or 10 bytes available in the buffer, we can try to do the whole varint deserialization from the buffer rather than byte by byte, and ultimately only consume the bytes we used. This lets us avoid the cost of going back and forth from the buffer 1-10 times.
