How is Amazon DynamoDB throughput calculated and limited?

Question

Is it averaged per second? Per minute? Per hour?

For example.. if I pay for 10 \"read units\" which allows for 10 highly consistent reads per second, will I be throttl

Answer 1

It appears that they track writes in a five minute window and will throttle you when your average over the last five minutes exceeds your provisioned throughput.

I did some testing. I created a test table with throughput of 1 write/second. If I don't write to it for a while and then send a stream of requests, Amazon seems to accept about 300 before it starts throttling.

The caveat, of course, is that this is not stated in any official Amazon documentation and could change at any time.
