Module nested_loop_join 

Nested Loop Join Operator.

This operator implements the classic nested loop join with O(N*M) complexity. It’s the fallback algorithm used when:

• No equality join keys exist (non-equi joins)
• Join condition uses complex expressions
• CROSS JOIN is requested

Despite its higher complexity, it supports all join conditions and types.
