DeltaStream is a serverless stream processing platform designed to simplify the development and operation of real-time streaming applications by bringing the benefits of relational data management to the streaming world. It enables users to build and manage secure, scalable, and reliable applications without the need for provisioning or maintaining servers, leveraging a familiar SQL database model to organize and secure data. DeltaStream offers seamless integration with multiple storage services like Apache Kafka and AWS Kinesis and ensures elasticity and fault tolerance with features like automatic checkpointing. The platform provides a REST API accessible via a web app, CLI, or direct integration, and is currently available on AWS with plans to expand to GCP and Azure. DeltaStream recently announced a $10 million seed funding round and launched a private beta for AWS users, seeking feedback to refine its offerings.
