> Adding consumer endpoints to polling components
> -----------------------------------------------

> Key: CAMEL-13292
> URL: https://issues.apache.org/jira/browse/CAMEL-13292
> Project: Camel
> Issue Type: Improvement
> Reporter: Kamesh Sampath
> Assignee: Andrea Cosentino
> Priority: Critical
>
> When camel is used in serverless world using camel-k, we need to start the
> routes as consumers of `knative` component.
> The following code gets the s3 file name as an event payload from a source ,
> but currently i cant use `s3` consumer to download the file and say log it as
> there is no consumer available in s3 component that can do it , if I make it
> from to be form s3 component then it becomes non-severless component i.e. not
> autoscalable. This pattern will be quite common in enterprise world and when
> using camel with serverless; hence its great to have consumers for all
> polling components to be used with knative/serverless scenarios.
> e.g.
> {code:java}
> from("knative:endpoint/s3filelogger") .log("Downloading file:
> ${in.header.fileName}")
> .setHeader(S3Constants.KEY,simple("${in.header.fileName}"))
> .toD("aws-s3://data?fileName=${in.header.CamelAwsS3Key}&deleteAfterRead=false")
> .idempotentConsumer(header("CamelAwsS3ETag"), idmRepo()) //just sending the
> response back to the callee .process(this::sendResponse) .end(); {code}
