------------------------------------------
PR opened: https://github.com/apache/camel/pull/26078
Adds the missing @Metadata constant for the realtime change type header and
uses it. The header name is unchanged, so this is metadata only.

> camel-google-firestore: the realtime change type header is undocumented
> -----------------------------------------------------------------------

> Key: CAMEL-24606
> URL: https://issues.apache.org/jira/browse/CAMEL-24606
> Project: Camel
> Issue Type: Bug
> Components: camel-google
> Reporter: Andrea Cosentino
> Assignee: Andrea Cosentino
> Priority: Minor
>
> The realtime consumer sets the document change type as a raw string literal:
> {code:java}
> if (changeType != null) {
> message.setHeader("CamelGoogleFirestoreChangeType", changeType.name());
> }
> {code}
> Every other header the component reads or writes is a {{@Metadata}}-annotated
> constant in
> {{GoogleFirestoreConstants}}, so it ends up in the component metadata. This
> one is not: the generated
> {{google-firestore.json}} documents 16 headers and this is not among them, so
> the only header that is
> specific to the realtime mode - the one telling the route whether a document
> was ADDED, MODIFIED or
> REMOVED - is invisible in the catalog, in the component documentation and in
> the endpoint DSL header
> accessors.
> The literal has been there since the component was contributed in CAMEL-23020.
> Add the missing constant and use it. The header name itself must NOT change:
> it is already emitted by the
> released component, so {{CamelGoogleFirestoreChangeType}} stays exactly as it
> is and only the metadata is
> added. No behaviour change, no upgrade note.
