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

             Summary: Forced join order SQL hint.
                 Key: CALCITE-5945
                 URL: https://issues.apache.org/jira/browse/CALCITE-5945
             Project: Calcite
          Issue Type: Task
            Reporter: Vladimir Steshin


For the join operations, we should have several SQL hints. One of them are 
forced join order hints. As an example, Oracle DB's analogue would be 
'ORDERED', 'LEADING'. Might be combined with join operation type like merge, 
hash, nl like 'USE_NL', 'USE_MERGE'
