>          Issue Type: Bug
>          Components: sql

> Now {{NestedLoopJoinNode}} uses internal buffer to save all rows of the right 
> input.
> We have to do refactoring {{IgniteNestedLoopJoin}} to use rewind of the right 
> input and use TableSpool for not rewindable inputs.
> This refactoring separates implementation the join logic from materialization 
> of the right input if it is needed. In the future we can use disk offload for 
> TableSpool etc.
