------------------------------------
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.
