SQL Stream BuilderPDF version

Running a simple SQL job

You can use this Getting Started use case to get familiar with the most simple form of running a SQL Stream job.

The Getting Started contains the basic steps of running a SQL Stream job. When executing the job, you do not need to select a sink as the results are displayed in the browser. The SQL Stream Builder provisions a job on your cluster to run the SQL queries. You can select the Logs tab to review the status of the SQL job. As data is returned, it shows up in the Results tab.
As the Getting Started is using the Stateful Tutorial as an example, you need to set up a Kafka topic as transaction.log.1 in Streams Messaging Manager, and submit the Kafka Data Generator job to generate data to the source topic. For more information, see the Stateful Tutorial.
