Sure, you could change the parser. I suggest you add a few tests to SqlParserTest and then change Parser.jj until the tests pass. You could then translate your query to the same as RelNode tree as “select * from A limit 10”, and Calcite can execute that.
Log a JIRA case describing the syntax you intend to implement.
