----------------------------------------
Summary: 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
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.
