Doug Cutting commented on THRIFT-765:
-------------------------------------
Milind claims in AVRO-532 that Hadoop's record io correctlly handled surrogate
pairs.
https://svn.apache.org/repos/asf/hadoop/common/branches/pre-HADOOP-4687/src/core/org/apache/hadoop/record/Utils.java
That code is quite different from the code in this patch. Notably, it calls
String#getCodePoint() and StringBuffer#appendCodePoint() to let Java implement
surrogate pairs.
> Improved string encoding and decoding performance

> 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.
