Description
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
- On project a source distribution key may appear more than once, so the result should contain a distribution for each distribution key position.
