主 题：[DICUSS] Support building physical RelNode in Calcite
Hi all,
In light of CALCITE
Hi all,
In light of CALCITE-2970, I’d like to initiate a discussion.
Currently the framework itself does not have a way to create physical RelNode
(RelNode with a particular convention). We completely rely on adapter rules to
convert logical nodes into physical ones. There are a few major
