> @Gabriel39 Thank you for your contribute! If the open phase is completed before the RF is generated, it may result in the generated expressions not being pushed down to the storage layer. It looks like this could lead to worse performance. We first need to provide runtime expressions to push down to the storage layer. Hi @stdpain @EmmyMiao87 , I got your point but one more thing I m not sure is whether open phase of scan node will be completed before RF is generated. For example, open() in `OlapScanNode` will be blocked until all RFs are ready. So it seems like scan node will execute with RFs without performance degradation. -- This is an automated message from the Apache Git Service.
