      Description

      Currently Ignite nodes have single distribution value which isn't true in several cases like:

      1. 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 implementĀ IGNITE-12692
      2. After inner / cross join the result should have several hash distributions (by left and by right keys) - it may be important onĀ join transpose optimization
      3. On project a source distribution key may appear more than once, so the result should contain a distribution for each distribution key position.
