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 
computing 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
