This sample shows how to use the TIBCO StreamBase® Avro to Tuple and Tuple to Avro operators.
The sample application illustrates 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 set up with a schema to try out various data types converting from tuples to Avro and back.
In StreamBase Studio, import this sample with the following steps:
From the top-level menu, click> .
avroto narrow the list of options.
Select Apache Avro from the Large Data Storage and Analysis category.
StreamBase Studio creates a single project for the operator samples.
In the Project Explorer view, open the sample you just loaded.
If you see red marks on a project folder, wait a moment for the project to load its features.
If the red marks do not resolve themselves after a minute, select the project, right-click, and select> from the context menu.
AvroConvert.sbappfile and click the button. This opens the SB Test/Debug perspective and starts the module.
In the Manual Input view, select the
Inputstream and enter some values then click .
In the Output Streams 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 Terminate EventFlow Fragment button.
When you load the sample into StreamBase Studio, Studio copies the sample project's files to your Studio workspace, which is normally part of your home directory, with full access rights.
Load this sample in StreamBase Studio, and thereafter use the Studio workspace copy of the sample to run and test it, even when running from the command prompt.
Using the workspace copy of the sample avoids permission problems. The default workspace location for this sample is:
