    March 23, 2025
    + 12

    The Couchbase Quarkus extension integrates the Couchbase Java SDK within the Quarkus ecosystem. Most notably this extension provides GraalVM native-image support to the existing Java SDK, in addition to other Quarkus integration such as Health Checks, ArC dependency injection, Micrometer metrics, DevServices and more.

    Key Features

    • Dependency Injection: Easily inject a Couchbase Cluster into your application using Quarkus' CDI.

    • Simplified Configuration: Manage Couchbase connection and cluster settings through application.properties.

    • Native-Image Support: Compatible with GraalVM/Mandrel for building native images.

    • Couchbase Operations: Support for KV, Query, Transactions, Analytics, Search, and Management operations.

    • Micrometer Metrics: Integrates with quarkus-micrometer.

    • Health Checks: Provides a readiness check via quarkus-smallrye-health.

    • Dev Services: Simplifies local development with automatic startup of a Couchbase TestContainer.

    Current Limitations

    • TLS Configuration: While connections to Couchbase Capella are supported by default using the couchbases:// scheme in dev mode, custom certificates or trust store configurations are not yet exposed.

    • OpenTelemetry Tracing: The tracing-opentelemetry package for the Couchbase Java SDK is not currently supported.

    • Exhaustive Cluster configuration: Cluster configurations via application.properties are limited to those listed below.
