> Path Template was introduced in FLINK-20264 with a new module YAML specification being added in FLINK-20334.
> However, that possibility was not added to the DataStream API.
> The main problem is that RequestReplyFunctionBuilder can only receive FunctionTypes which it then turns into FunctionTypeTarget's for the HttpFunctionEndpointSpec builder:
> {code:java}
> private RequestReplyFunctionBuilder(FunctionType functionType, URI endpoint) {
>   this.builder =
>       HttpFunctionEndpointSpec.builder(
>           Target.functionType(functionType), new UrlPathTemplate(endpoint.toASCIIString()));
> }
> {code}
> It should also be possible for the RequestReplyFunctionBuilder to receive a namespace instead of a function type and to use `Target.namespace(namespace)` to initialize the HttpFunctionEndpointSpec Builder instead.
