Elaborate.

The whole auto-balancing thing isn't instant. If you have a burst of writes with the same key prefix, you'll get throttled.

Not the OP but I’ve had AWS-staff recommend different prefixes even as recently as last year.

If key prefixes don’t matter much any more, then it’s a very recent change that I’ve missed.

Might just be that the AWS staff wasn't up to date on this

That's right, same for me as of only a few months ago.
