BTW when statistics support range estimates, we will not need to hardcode any assumption like 20% within how the operator reports the statistics. In this specific example, the filter would say it could be anything between 0 and the incoming number of rows, which is accurate. The logic that consumes these stats is now free to make any heuristic assumptions it wants to make on top of this information. -- This is an automated message from the Apache Git Service.
