      Description

      If the query is super large, e.g. contains tens of thousands of nodes or expressions, the RelNode digest and desc become very large. The content of desc and digest are almost the same, except that desc consists of id plus digest, which causes OOM in our production system. So remove desc, just use id + digest to produce description.
