I think you should actually just put the function in Drill itself. System native functions are implemented in the same interface as UDFs, because our mechanism for evaluating them is very efficient (we code generate code blocks by linking together the bodies of the individual functions to evaluate a complete expression).
You can open a JIRA, marking it a feature request. You can open a poll request against the apache github repo, making sure you follow the standard format for your commit message, prefixing with the JIRA number in the format Example: DRILL-XXXX: Feature description This will automatically link the PR to your JIRA. - Jason On Thu, Feb 4, 2016 at 8:44 AM, Nicolas Paris <nipari...@gmail.com> wrote: > Jason, I have it working, > > Just tell me the way to proceed to PR. > 1. where do I put my maven project ?
