Atri Sharma commented on CALCITE-500:
-------------------------------------

[~julianhyde] I see no unit tests with any of the EnumerableJoins. Is there a 
comprehensive way to trigger the rule, or could you suggest a strategy to write 
a unit test for the same please?

> Ensure EnumerableJoin hashes the smallest input

> {{EnumerableJoin}} tries to put the smallest input the first, however when it 
> comes to execution, Calcite creates lookup for _second_ input of join.
> It would be nice to ensure the lookup is created on the smallest input.
