Apologies if this would be a better fit for the user mailing list, but I was unsure where to ask questions on (yet) unreleased functionality.
I was really happy when I realized that FLINK-20334 <https://issues.apache.org/jira/browse/FLINK-20334> was adding Path Templating, but it seems to me that the possibility was not added to the Data Stream API. I may be misunderstanding the codebase, but in SerializableHttpFunctionProvider#48 the HttpFunctionProvider is always instantiated with an empty map of perNamespaceEndpointSpecs, which would be easy to change in the StatefulFunctionDataStreamBuilder. Is there a reason this wasn't considered? Is there anything tricky that is blocking this addition, or maybe path templating is not relevant for the DataStream API and I'm not seeing the most appropriate way to achieve the same goal? Thanks, Miguel
