Stream into Imply Polaris with your free account

The Imply Polaris materialization connector in Estuary streams data from Estuary collections to Imply Polaris as Kafka-compatible messages using Dekaf. Imply Polaris can consume these streams through its Kafka ingestion interface for real-time analytics on streaming and batch data.

• Kafka-compatible streaming from Estuary collections to Imply Polaris
• No separate Kafka cluster required — Imply Polaris connects directly to Estuary’s Dekaf endpoint
• One or more Estuary collections can be exposed as Kafka-compatible topics
• Configurable topic names for individual collection bindings
• Avro message format for ingestion into Imply Polaris
• Schema Registry support, allowing Imply Polaris to detect the Avro schema automatically
• Kafka or CDC deletion modes for controlling how deletions are represented
• Optional strict Kafka-compatible topic naming
• SASL/SSL authentication using the materialization name and an authentication token

To connect Imply Polaris, configure a Kafka input using dekaf.estuary-data.com:9092 as the bootstrap server, SASL_SSL with the PLAIN mechanism, and the Estuary materialization name and auth token as the Kafka credentials. Imply Polaris can then ingest the Avro stream and detect its schema through Estuary’s Schema Registry endpoint.
