How to integrate Apache Kafka with CrateDB (Beta) in 3 simple steps
Connect Apache Kafka as your data source
Set up a source connector for Apache Kafka in minutes. Estuary supports streaming (including CDC where available) and batch data capture through events, incremental syncs, or snapshots — without custom pipelines, agents, or manual configuration.
Configure CrateDB (Beta) as your destination connector
Estuary supports intelligent schema handling, with schema inference and evolution tools that help align source and destination structures over time. It supports both batch and streaming data movement, reliably delivering data to CrateDB (Beta).
Deploy and Monitor Your End-to-End Data Pipeline
Launch your pipeline and monitor it from a single UI. Estuary guarantees exactly-once delivery, handles backfills and replays, and scales with your data — without engineering overhead.

Apache Kafka connector details
The Apache Kafka connector captures high-volume streaming data from Kafka topics into Estuary collections with support for both Avro and JSON message formats. It integrates seamlessly with Schema Registry for schema discovery and exactly-once delivery across distributed topics.
- Captures real-time Kafka streams from multiple topics
- Supports Avro and JSON message formats
- Integrates with Schema Registry for key and schema management
- Compatible with SASL/SCRAM, AWS IAM, and TLS authentication
- Secure deployment within Estuary’s Private and BYOC environments for compliance and governance
💡 Tip: Works with Confluent Cloud, AWS MSK, and other managed Kafka services. For best results, enable TLS and schema registry support to maintain schema integrity.
