For example `--spring.cloud.stream.poller.fixed-delay=2000` sets the poller interval to poll every two seconds.
For example `--spring.integration.poller.fixed-delay=2000` sets the poller interval to poll every two seconds.
IMPORTANT: These poller properties are deprecated starting version 3.2 in favor of similar configuration properties from Spring Boot auto-configuration for Spring Integration.
See `org.springframework.boot.autoconfigure.integration.IntegrationProperties.Poller` for more information.
====== Per-binding polling configuration
The previous section shows how to configure a single default poller that will be applied to all bindings. While it fits well with the model of microservices spring-cloud-stream designed for where each microservice represents a single component (e.g., Supplier) and thus default poller configuration is enough, there are edge cases where
you may have several components that require different polling configurations
For such cases please use per-binding way of configuring poller. For example, assume you have an output binding `supply-out-0`. In this case you can configure poller for such
binding using `spring.cloud.stream.bindings.supply-out-0.producer.poller..` prefix (e.g., `spring.cloud.stream.bindings.supply-out-0.producer.poller.fixed-delay=2000`).
