John Wang updated THRIFT-3032:
------------------------------
Description: A "TBaseProcessor" uses a map to store all the methods of a
service. I suggest that a array or "ArrayList" should be used. Methods can be
identified by indices for which the worst-case complexity is O(1) while compute
hash code for a string is not. To achieve this goal, we may tell the compiler
to generate a enumeration constant list of all the methods per service. The
ordinals of the enumeration constants need to be package into the messages
rather than the name of methods. And in theory network overhead should be
reduced additionally. (was: A "TBaseProcessor" uses a map to store all the
