>                 Key: IGNITE-12899
>                 URL: https://issues.apache.org/jira/browse/IGNITE-12899
>             Project: Ignite
>          Issue Type: Task
>            Reporter: Igor Seliverstov
>            Priority: Minor
>              Labels: calcite2-required, calcite3-required

> 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.
