[jira] [Created] (IGNITE-14306) Calcite. Hints support

Yury Gerzhedovich created IGNITE-14306:
------------------------------------------

             Summary: Calcite. Hints support
                 Key: IGNITE-14306
                 URL: https://issues.apache.org/jira/browse/IGNITE-14306
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Yury Gerzhedovich


We need to introduce hints for the new SQL engine.
At least it could be planner hints, like an ENFORCE JOIN ORDER, Algorithm of join, switch on/off some planer rules. Maybe we could pass as a hint the whole execution plan, or modify some parameters, like costs.
