Yeah I should have elaborated a bit. I believe adaptive capacity was announced at re:invent in 2017 and may have released shortly after / maybe early 2018. The feature is getting a lot more press & push from AWS lately though for sure.
I remember having a conversation with our AWS rep about 2 years ago during our quarterly feature request meeting. I remember asking for DynamoDB autoscaling and burst capacity; pretty happy they finally delivered.
Since then we've pretty much cut our DynamoDB bill in half and had a drastic reduction in throttled responses.
