------------------------------------

             Summary: Avoid errors when identifiers use reserved keywords
                 Key: FLINK-23019
                 URL: https://issues.apache.org/jira/browse/FLINK-23019
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / API
            Reporter: Timo Walther


We add more and more keywords and built-in functions with special meaning to SQL. However, this could be quite annoying for users that have columns named like a keyword. E.g. {{timestamp}} or {{current_timestamp}}.

We should investigate if we can do better and avoid forcing escaping with backticks. IIRC  Calcite also offers functionalities for that.
