Event Streaming Database

Easily build real-time applications that leverage stream processing

Confluent, via ksqlDB, enables you to build modern, data-in-motion applications with the same ease and familiarity of building traditional applications on a relational database. It also simplifies the underlying architecture for these applications, so you can build powerful, real-time systems with just a few SQL statements.



The latest features of the project, delivered monthly to optimize release agility. Supported by the community.
