This sample shows how to use the TIBCO StreamBase® Avro to Tuple and Tuple to Avro operators.
The sample application illustrate the use of the Avro to Tuple and Tuple to Avro operators. In this sample, the operator takes an input tuple and produces an Apache Avro Record blob, it then takes that blob and produces a tuple. The sample is setup with a schema to try out various data types converting from tuples to Avro and back.
In the Package Explorer view, in project
sample_avro, double-click to open the
AvroConvert.sbappapplication selected and active, click the button. This opens the SB Test/Debug perspective and starts the application.
In the Manual Input view, select the
Inputstream and enter some values then click .
In the Application Output view, observe a tuple dequeued on the
Experiment by entering other values in the fields of the
TestInputstream, clicking , and observing the resulting output tuples.
When done, press F9 or click the Stop Running Application button.
