org.apache.flink.table.planner.parse.ExtendedParser

public class ExtendedParser
extends Object

ExtendedParser is used for parsing some special command which can't supported by CalciteParser, e.g. SET key=value may contain special characters in key and value. It's also a good idea to move some parsing strategy here to avoid introducing new reserved keywords.
