DynamoDB is not a memory store, it is a fully managed NoSQL database service offered by Amazon Web Services (AWS). It is designed to provide fast and predictable performance with seamless scalability. DynamoDB uses solid-state drives (SSDs) for data storage, which provides fast access to data and enables the service to handle high request rates.
That being said, DynamoDB has a feature called DynamoDB Accelerator (DAX), which is an in-memory cache supplementing DynamoDB tables that delivers fast read performance for your tables at scale by enabling you to use a fully managed in-memory cache.
