[jira] [Updated] (ARROW-3459) Add support for variable length output vectors

     [ https://issues.apache.org/jira/browse/ARROW-3459?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.
