Now that your data is in motion, it’s time to make sense of it. Stream processing enables you to derive instant insights from your data streams, but setting up the infrastructure to support it can be complex. That’s why Confluent developed ksqlDB, the database purpose-built for stream processing applications.
Make your data immediately actionable by continuously processing streams of data generated throughout your business. ksqlDB’s intuitive syntax lets you quickly access and augment data in Kafka, enabling development teams to seamlessly create real-time innovative customer experiences and fulfill data-driven operational needs.
ksqlDB offers a single solution for collecting streams of data, enriching them, and serving queries on new derived streams and tables. That means less infrastructure to deploy, maintain, scale, and secure. With less moving parts in your data architecture, you can focus on what really matters -- innovation.
Build real-time applications with the same ease and familiarity as building traditional apps on a relational database -- all through a familiar, lightweight SQL syntax. How does Kafka Streams compare to ksqlDB? Well. ksqlDB is built on top of Kafka Streams, a lightweight, powerful Java library for enriching, transforming, and processing real-time streams of data. Having Kafka Streams at its core means ksqlDB is built on well-designed and easily understood layers of abstractions. So now, beginners and experts alike can easily unlock and fully leverage the power of Kafka in a fun and accessible way.
Query tables and streams by either continuously subscribing to changing query results as new events occur (push queries) or looking up results at a point in time (pull queries), removing the need to integrate separate systems to serve each.
Eliminate the operational burden of running your own infrastructure for ksqlDB by leveraging a fully managed service in Confluent Cloud. With self-serve provisioning, in-place upgrades and guaranteed 99.95% uptime SLA, you can focus on building useful application functionality and not managing clusters.
Extend ksqlDB with custom functions that are specific to your use case. Leverage Java to express your own data processing logic, exposing it to the ksqlDB engine using convenient hooks.
Easily move data streams from existing systems in and out of ksqlDB. Rather than running a separate Kafka Connect cluster for capturing events, ksqlDB can run pre-built connectors directly on its servers.
Rest assured your data is protected by leveraging ksqlDB alongside Role-Based Access Control, Audit Logs, and Secret Protection. Confluent designs products with security in mind, making ksqlDB secure by default.

"With the reactive infrastructure we’ve built using Confluent Cloud and the ability to query streams in real time with ksqlDB, we are better able to apply machine learning algorithms that optimize campaigns for our customers. ksqlDB is tremendously powerful for us because it enables us to be flexible with our data mapping in a way that many of our competitors cannot.“
