To be clear, I would *much* rather rely on Datafusion to implement the core physical operators (since they do it much better, and we get performance improvements for free), the only caveat being we will need to ensure we can get the same or better read amplification the current native JDK Druid code does, e.g. where we can rely on column stats, row count, bitmap/dictionary indices to pushdown filters/projections and avoid decompressing/scanning more than we need to. -- This is an automated message from the Apache Git Service.
