AuroraDB MySQL Cloning: How fast is it?

Thank you for asking your question.

Unfortunately, currently we don't have SLA on Aurora database cloning. It depends on various conditions. One note here is after you have 15 clones, the next clone that you create is a full copy, it means clone takes longer time than usual. We highly recommend do a test with real workload before using new feature.

Please see our document for more detail.
