I think using Datafusion would be a good idea (much better than the current query planner/execution engine set up), but one thing to call out here is that Datafusion always materializes rows into ArrowBatch between operators, which is a bit different in some cases compared to Druid. This materialization cost can be expensive. -- This is an automated message from the Apache Git Service.
