CrateDB is a hyper-fast opensource distributed database technology that combines the best out of the SQL and NoSQL worlds. It supports the PostgreSQL wire protocol for easy integration with many data engineering tools.
Dapr (Distributed Application Runtime) provides APIs that simplify microservice connectivity. Whether your communication pattern is service to service invocation or pub/sub messaging, Dapr helps you write resilient and secured microservices.
Dapr supports connecting to PostgreSQL, and therefore CrateDB, as an output binding and as a state store. By leveraging this capability, users can easily tap into the power of CrateDB and harness its potential for efficient data management and storage.
