We definitely plan on contributing it to druid, so that's great to hear. 🙂 I hadn't considered pointing it at a different data source. So, basically, we could identify when data started arriving at the new data source, and copy all the old data in prior to that. Or, keep the old one around, and stitch it together in the app. Unfortunately for us we have a few years' worth of data (not a huge amount, so copying it around is likely feasible).
