I'm actually impressed at how incredibly expensive they made this. $0.50 per million 1KB writes, which is 20x what aurora charges, since aurora allows 8KB writes. And Aurora is already expensive if you actually read/write to it.
That's a weird comparison. 20x is only true if you write 8KB with every entry, and you haven't included the storage and instance savings.
It's not hard to come up with suboptimal scenarios where this is more expensive, but that's missing the point. It's optimized for a specific kind of usage pattern.
Curious to see what the query language is for this, wonder if they're just exposing the backing store for CloudWatch as a service now.
