There has been discussion recently on Drill's goal of integrating with
Arrow. The work to use the `Drillbuf` highlights how we can integrate with
Arrow. Simply replace the `Drillbuf` usage with `ArrowBuf`, make the required
changes in vector names, add a few methods to the Arrow API, and this entire
mechanism can be easily ported over to use Arrow.---
