Public preview: Job diagram simulator in VS Code

Published date: October 12, 2022

One way to optimize a Stream Analytics job’s performance is to leverage parallelism in query. The job diagram simulator in VS Code allows you to simulate the job running topology with different streaming units (SUs) and provide suggestions for improving your query’s parallelism as you develop the streaming query. If your job does not run in parallel, the job simulator will highlight the query steps that are not partitioned correctly with corresponding line numbers. Then you can change the queries and/or configurations based on the suggestions provided to make it a parallel job.
