Any column used in constraints? That sounds risky!

A technical or surrogate key is usually the best choice.

I’m leaning towards any column used in table constraints, but I need to double-check if that’s always a valid choice for distribution keys.

I feel like low cardinality columns could lead to issues, but I can't recall the specifics on why that might be a problem.

I remember practicing a question about distribution keys, and I think any date column commonly used in queries could be valid too.

I think a technical or surrogate key might be a good choice, but I'm not entirely sure if it's the best option for performance.

Hmm, this seems straightforward. I think the gender field should be on the Contact object since that's where the gender information is typically stored.

Adding a rewrite rule for the host header seems like a reasonable approach based on the information provided. I'll walk through the steps to implement that and see if it resolves the issue.
