### Is your feature request related to a problem or challenge? Currently the `null_equals_null` flag in DF joins is hard-coded to false across multiple places in the code. It is not configurable either from a query or session configuration. We need to make this flag configurable to allow more flexibility in how joins handle null values. ### Describe the solution you'd like I am not sure which alternative is more useful and expected, and I couldn't find any examples. If we select it as a session config, users will need to change the setting for each preference change. On the other hand, if it is provided within the query, users must explicitly specify it for each non-default case. ### Describe alternatives you've considered Perhaps both solutions can coexist. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
