[jira] [Created] (IGNITE-15323) Calcite engine. Query lifecycle refactoting

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

             Summary: Calcite engine. Query lifecycle refactoting
                 Key: IGNITE-15323
                 URL: https://issues.apache.org/jira/browse/IGNITE-15323
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Taras Ledkov
            Assignee: Taras Ledkov


Motivation and goals:
- introduce a {{Query}} abstraction to track a query on all phases: planning, mapping, execution;
- use one place to query management
- try to make query phases more isolated, e.g.. now {{PlanningContext}} contains AffinityTopologyVersion and node IDs. It looks like this information has nothing to do with the query planning.
