Amazon Neptune Client

List of execution interceptors that will have access to read and modify the request and response objects as they are processed by the AWS SDK.

The list should consists of class names which implements software.amazon.awssdk.core.interceptor.ExecutionInterceptor interface. Classes will be attempted to be loaded via CDI first, and if no CDI beans are available, then the constructor with no parameters will be invoked to instantiate each class.

Environment variable: QUARKUS_NEPTUNE_INTERCEPTORS

OpenTelemetry AWS SDK instrumentation will be enabled if the OpenTelemetry extension is present and this value is true.

Environment variable: QUARKUS_NEPTUNE_TELEMETRY_ENABLED

Type of the sync HTTP client implementation

Environment variable: QUARKUS_NEPTUNE_SYNC_CLIENT_TYPE

Type of the async HTTP client implementation

Environment variable: QUARKUS_NEPTUNE_ASYNC_CLIENT_TYPE

If a local AWS stack should be used. (default to true) If this is true and endpoint-override is not configured then a local AWS stack will be started and will be used instead of the given configuration. For all services but Cognito, the local AWS stack will be provided by LocalStack. Otherwise, it will be provided by Moto

Environment variable: QUARKUS_NEPTUNE_DEVSERVICES_ENABLED

Indicates if the LocalStack container managed by Dev Services is shared. When shared, Quarkus looks for running containers using label-based service discovery. If a matching container is found, it is used, and so a second one is not started. Otherwise, Dev Services starts a new container.

The discovery uses the quarkus-dev-service-localstack label. The value is configured using the service-name property.

Sharing is not supported for the Cognito extension.

Environment variable: QUARKUS_NEPTUNE_DEVSERVICES_SHARED

Indicates if shared LocalStack services managed by Dev Services should be isolated. When true, the service will be started in its own container and the value of the quarkus-dev-service-localstack label will be suffixed by the service name (s3, sqs, …​)

Environment variable: QUARKUS_NEPTUNE_DEVSERVICES_ISOLATED

The value of the quarkus-dev-service-localstack label attached to the started container. In dev mode, when shared is set to true, before starting a container, Dev Services looks for a container with the quarkus-dev-service-localstack label set to the configured value. If found, it will use this container instead of starting a new one. Otherwise it starts a new container with the quarkus-dev-service-localstack label set to the specified value. In test mode, Dev Services will group services with the same service-name value in one container instance.

This property is used when you need multiple shared LocalStack instances.

Environment variable: QUARKUS_NEPTUNE_DEVSERVICES_SERVICE_NAME

Generic properties that are pass for additional container configuration.

Environment variable: QUARKUS_NEPTUNE_DEVSERVICES_CONTAINER_PROPERTIES__CONTAINER_PROPERTIES_
