salesforce pubsub source Salesforce Pub/Sub Source

Provided by: "Apache Software Foundation"

Support Level for this Kamelet is: "Preview"

Receive events from the Salesforce Pub/Sub API.

This is the gRPC based Pub/Sub API, not the older streaming API that salesforce-source uses. Subscribe to a channel such as /event/MyEvent__e, /topic/MyTopic or /data/AccountChangeEvent.

The Pub/Sub API is gRPC based and needs a protobuf-java new enough for the generated stubs in camel-salesforce. Under Camel JBang an older protobuf is resolved and the route fails to start with NoClassDefFoundError on com.google.protobuf.RuntimeVersion; adding protobuf-java as an explicit dependency resolves it.

  • camel:core

  • camel:salesforce

  • camel:kamelet

Camel JBang usage

Prerequisites

  • You’ve installed JBang.

  • You have executed the following command:

jbang app install camel@apache/camel

Supposing you have a file named route.yaml with this content:

- route:
    from:
      uri: "kamelet:salesforce-pubsub-source"
      parameters:
        .
        .
        .
      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command

camel run route.yaml
