RisingWave is a distributed streaming SQL platform that ingests, transforms and serves real-time data using PostgreSQL-compatible SQL. Thanks to built-in storage it serves low-latency queries without separate databases, caches or message queues. You can run RisingWave yourself as open-source software, use it as a managed service (RisingWave Cloud), or run it in your own AWS, GCP or Azure account through bring-your-own-cloud.
RisingWave Labs is based in San Francisco. The core engine is licensed under Apache 2.0 and can be self-hosted free of charge. With bring-your-own-cloud, the entire data plane runs in your own cloud account and you choose the region, so data can stay in a European region; the control plane, however, is operated by RisingWave. A European organisation that wants to keep control of its data can consider self-hosting or bring-your-own-cloud in an EU region.
