zabetak opened a new pull request, #4079: URL: https://github.com/apache/calcite/pull/4079
The `RelMdUniqueKeys#getPassedThroughCols` method exists only for performing a cross product of the various mappings between input and output "pass through" columns. The entire method can be replaced by exploiting the built-in `Linq4j#product` API and few other utility methods. After the refactoring the code is easier to follow and potentially more efficient since the result is computed gradually and we don't have to retain the entire cross product result in memory. -- This is an automated message from the Apache Git Service.
