Get a document from Couchbase Server via Key/Value access. The ID of the document to fetch may be supplied by setting the <Document Id> property. NOTE: if the Document Id property is not set, the contents of the FlowFile will be read to determine the Document Id, which means that the contents of the entire FlowFile will be buffered in memory.
