Zheng Shao commented on HIVE-563:
---------------------------------
Agree with Raghu. While the String comparisons are still OK (I think moving to
the static hashmap will definitely help but it's optional to do), doing
"String.split()" is really a big performance hit (this is part of the reason
that scripting languages are somehow slower - just because people like to use
String.split() in those languages)
Can we cache "partToExtract" from last call, and avoid doing String.split again
if the "partToExtract" didn't change (which is the normal case).
Can we do a loop through the query string instead of calling String.split?
