Bryan Duxbury updated THRIFT-765:
---------------------------------
Attachment: thrift-765.patch
This patch adds a new class, Utf8Helper, that implements the fast encoding and
decoding methods. It also changes Binary and Compact protocols to use this
method of encoding.
I haven't benchmarked the overall performance improvements to the respective
protocols, but I did perform a micro-benchmark of string encoding and decoding,
which showed the new methods take about half as long. The benefit you see in
your actual serialization/deserialization will depend on how many strings you
use.

> One of the most consistent time-consuming spots of Thrift serialization and
> deserialization is string encoding. For some inscrutable reason,
> String.getBytes("UTF-8") is slow.
> However, it's recently been brought to my attention that DataOutputStream's
> writeUTF method has a faster implementation of UTF-8 encoding and decoding.
> We should use this style of encoding.
