Microservice architectures create loose couplings between data and applications and offer greater development agility. In such architectures, service-to-service communication can lead to brittleness that can result in cascading failures, which in turn impact the reliability of your business operations. Using CDC for Astra DB to invoke other microservices in response to a data change event in one microservice domain can strengthen the overall reliability of your microservice architecture.

A “CDC Read Request Unit” (RRU) is the unit of measure for billing CDC reads.
It is based on the payload of each read query response.
CDC for Astra DB performs a database read for each CDC enabled write. These reads are reflected on the bill as CDC Read Request Units.
A CDC Read Request that returns up to 4KB of data is considered an RRU. If the request returns more than 4KB of data, additional CDC RRUs are required.
