---------------------------------------
Summary: Support Salesforce Streaming API Server-Initiated
Disconnect Messages
Key: CAMEL-24569
URL: https://issues.apache.org/jira/browse/CAMEL-24569
Project: Camel
Issue Type: Improvement
Components: camel-salesforce
Affects Versions: 4.22.0
Reporter: Bartosz Popiela
Starting with Salesforce Streaming API version 64.0, the Salesforce server can
send disconnect messages to connected Streaming API clients via the
{{/meta/disconnect}} channel.
These server-initiated disconnects can occur as a result of infrastructure
auto-scaling and are expected to happen more frequently on Salesforce
Hyperforce instances. When such a disconnect occurs, clients are required to
reconnect to the Streaming API endpoint to keep their subscriptions active.
The Apache Camel Salesforce component should be enhanced to support this
behavior.
The Salesforce Streaming API client should:
* Register a listener for the {{/meta/disconnect}} CometD channel.
* Detect server-initiated disconnect messages.
* Trigger reconnection to the Salesforce Streaming API endpoint after
receiving a disconnect message.
* Restore existing Streaming API subscriptions after reconnecting.
* Ensure the reconnection mechanism integrates with the component's existing
connection and retry/recovery logic.
* Provide appropriate logging to make server-initiated disconnects and
subsequent reconnection attempts observable.
This change is required to ensure reliable long-running Salesforce Streaming
API subscriptions with API version 64.0 and later, particularly for Salesforce
Hyperforce environments where server-initiated disconnects can occur more
frequently.
