DynamoDB

As explained in ScyllaDB in Action

Amazon DynamoDB is a fully managed cloud key-value and document database service.

DynamoDB is Amazon Web Services’ key-value store and document database interface. ScyllaDB exposes compatibility through its Alternator protocol, allowing a DynamoDB client to connect directly. section 8.2.3

Treat the compatibility as an API layer rather than identical internals: ScyllaDB still uses partition keys, data compaction, repairs, and its own distributed architecture. Read-modify-write guarantees may require lightweight transactions and can reduce performance, so new ScyllaDB applications are generally better served by CQL. section 8.2.3
