             Summary: Add Limit and LogicalLimit operator and deprecate limit in Sort
                 Key: CALCITE-4058
                 URL: https://issues.apache.org/jira/browse/CALCITE-4058
             Project: Calcite
          Issue Type: New Feature
          Components: core
            Reporter: Haisheng Yuan


Add {{Limit}} base class and {{LogicalLimit}} operator.
Fetch and offset should not be in Sort operator, we should deprecate the fields while keeping the Sort work for compatibility.

{code:java}
select * from foo limit 5 offset 3;
select * from foo order by a;
{code}

The above 2 queries are totally different query, but have the same operators, SortxxxTranspose sometimes means limit push down, which is counter-intuitive.
