I feel like columns used for joins could also be significant, but I can't recall if it was specifically highlighted in our study materials.

I think one important factor might be the columns used for filters, but I'm not entirely sure if that's the best choice.

I've got this! The key things to look at are the data distribution, like how many distinct values there are, and whether the columns have any constraints like NOT NULL. Those will be crucial in selecting an effective distribution key.

Okay, for distribution keys, I'd say the top factors are the columns used for filtering and joining data. Those are going to have the biggest impact on query performance and data skew.

This seems like a straightforward question. I'll focus on the key factors that affect distribution, like the cardinality of the columns and how they're used in queries.

I'd go with A and E. Those table-level constraints can really impact the performance of your distribution, so they're crucial to consider.

Haha, I can't believe they didn't include 'table size' as an option. That's gotta be the most important factor, right? How else will I know where to stash my 'Big Data'?

C is definitely a key factor. The distribution key should be based on the distinct values in the column to ensure even distribution of data.
