[jira] [Created] (IGNITE-12899) Calcite integration. Distribution multitrait

Igor Seliverstov created IGNITE-12899:
-----------------------------------------

             Summary: Calcite integration. Distribution multitrait
                 Key: IGNITE-12899
                 URL: https://issues.apache.org/jira/browse/IGNITE-12899
             Project: Ignite
          Issue Type: Task
            Reporter: Igor Seliverstov


Currently Ignite nodes have single distribution value which isn't true in several cases like:
 # a partitioned table with a key alias should have 2 distribution traits: by _key and by key alias (id for example) - without distribution by _key column almost impossible to implement IGNITE-12692
 # After inner / cross join the result should have several hash distributions (by left and by right keys) - it may be important on join transpose optimization
