Since the result of a SQLExecute always goes in the flowfile content and we are executing more than one query in series, we have to move the content from the first query to an attribute with the ExtractText processor. You can even leverage NiFi as a basic syslog load balancer. You can construct arrays of simple data types, such as INT64, and complex data types, such as STRUCTs. Content is the data that is represented by the FlowFile.
