Improvements to varint reading in Compact Protocol
--------------------------------------------------
Key: THRIFT-754
URL: https://issues.apache.org/jira/browse/THRIFT-754
Project: Thrift
Issue Type: Improvement
Components: Library (Java)
Affects Versions: 0.3
Reporter: Bryan Duxbury
Assignee: Bryan Duxbury
Fix For: 0.3
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.
