-|spring.cloud.stream.metrics.schedule-interval | `60s` | Interval expressed as Duration for scheduling metrics snapshots publishing. Defaults to 60 seconds
 |spring.cloud.stream.output-bindings |  | A semi-colon delimited string to explicitly define output bindings (specifically for cases when there is no implicit trigger to create such bindings such as Function, Supplier or Consumer).
 |spring.cloud.stream.override-cloud-connectors | `false` | This property is only applicable when the cloud profile is active and Spring Cloud Connectors are provided with the application. If the property is false (the default), the binder detects a suitable bound service (for example, a RabbitMQ service bound in Cloud Foundry for the RabbitMQ binder) and uses it for creating connections (usually through Spring Cloud Connectors). When set to true, this property instructs binders to completely ignore the bound services and rely on Spring Boot properties (for example, relying on the spring.rabbitmq.* properties provided in the environment for the RabbitMQ binder). The typical usage of this property is to be nested in a customized environment when connecting to multiple systems.
 |spring.cloud.stream.pollable-source | `none` | A semi-colon delimited list of binding names of pollable sources. Binding names follow the same naming convention as functions. For example, name '...pollable-source=foobar' will be accessible as 'foobar-iin-0'' binding
