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.
StreamSets is a lightweight and powerful engine that allows you to build streaming, batch and change-data-capture (CDC) pipelines that can ingest and transform data from a variety of different sources.
StreamSets Data Collector can be paired with CrateDB either as an endpoint or as a source for the pipelines you create, leveraging CrateDB's scalable storage and real-time query capabilities.
