[jira] [Created] (IGNITE-14307) Calcite. Use statistics in cost model.

Yury Gerzhedovich created IGNITE-14307:
------------------------------------------

             Summary: Calcite. Use statistics in cost model.
                 Key: IGNITE-14307
                 URL: https://issues.apache.org/jira/browse/IGNITE-14307
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Yury Gerzhedovich


Currently, we use only table size for the cost model, however as [IEP-58|https://cwiki.apache.org/confluence/display/IGNITE/IEP-58%3A+Statistics+for+SQL+query+optimization] will be implemented we could use it to improve our cost model,
