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.
Hmm, I'm a bit unsure about this one. I know distribution keys are important for performance, but I'm not totally clear on all the specific considerations. I'll have to think it through carefully.
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.
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'?
I think B and D are the most important factors to consider. The distribution key should be based on the columns used for filtering and joining the data.
