lookup между двумя базам.

был бы хорошо если добавили бы возможность делат lookup db1.collection1.aggregate => db2.collection2.aggregate

Lookup between 2 database

It will be good to have ability to lookup between 2 databases like that:

lookup db1.collection1.aggregate => db2.collection2.aggregate

This is possible in SQL like database:

SELECT ...
FROM A.table t1
JOIN B.table2 t2 ON t2.column = t1.col

Thank you for a great job and your online university program, goog luck !!!
