Wait, are we sure these are all the right answers? I thought there was supposed to be a 'none of the above' option for these tricky AWS questions.

Because splitting the files to match the number of slices in the Redshift cluster will optimize the COPY process.

Haha, Shawna's got a point. If you have a skewed distribution on that DISTKEY, option D could be a real game-changer. Gotta love those database optimization tricks!

Hold on, what if I have a really big DISTKEY column? Wouldn't option D be even better by sharding the files based on that?

I was thinking the same thing. Compressing and uploading the files to S3 in a way that aligns with the Redshift architecture is a smart move.

B: D) Apply sharding by breaking up the files so that the DISTKEY columns with the same values go to the same file. Compress and upload the sharded files to Amazon S3. Run the COPY command on the files.

A: B) Split the files so that the number of files is equal to a multiple of the number of slices in the Redshift cluster. Compress and upload the files to Amazon S3. Run the COPY command on the files.
