RR

The RR serves as the frontend in the DynamoDB system architecture. These are stateless hosts responsible for routing requests to other service components based on the nature of the requests. Being stateless means that there is no specific allocation of RR hosts for different customers; any RR can process requests for any customer. RRs are designed to handle all types of DynamoDB requests from end users, including both data plane and control plane requests.

In the context of DynamoDB, data plane requests directly interact with table data. For instance, create, read, update, and delete (CRUD) operations that act on the data itself are considered data plane requests. On the other hand, control plane requests involve managing DynamoDB data in various ways. Examples of control plane requests in DynamoDB include creating, deleting, or updating a table, modifying a table’s provisioned capacity, or enabling/disabling a DynamoDB Stream for a table.
