> [C++][Gandiva] Add support for variable length output vectors
> -------------------------------------------------------------
>
> Key: ARROW-3459
> URL: https://issues.apache.org/jira/browse/ARROW-3459
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++ - Gandiva
> Reporter: Pindikura Ravindra
> Assignee: Pindikura Ravindra
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.14.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> 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.
