Pindikura Ravindra updated ARROW-3459:
--------------------------------------
    Description: 
Gandiva can currently handle variable length input vectors but requires the 
output vectors to be fixed-length. This is because we do not have a handle to 
allocate or resize arrow vectors from inside the LLVM code. Due to this 
limitation, we are not able to support a lot of utf8 related functions 
(convert-numeric-to-string, toupper, strstr, replace, ..).

 

This needs to be fixed for both C++ and Java.
