>When the leftChildFragment 's has no data and returned num nodes 0, the returned num nodes should be changed to 1. Because for a scan node has no data,there will be as least a random selected node for it. The broadcast cost calculation is right. You should fix the `getNumInstances` method in `OlapScanNode`. the getNumInstances result at least to 1. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
