Source to Topic Matching
A topic can belong to several sources. Each source must match the type of the topics which belong to it. For example, “CSV” or “JDBC”. This matching is configured via the properties described here.
At request time, if a requested topic resolves to more than one source you must clarify
which source to operate on by using the sourceType and/or the sourceName parameters of the request.
