Configure Deployment Settings

Before deploying the application, you must configure deployment settings such as JVM size, number of ackers, and number of workers. Because this topology uses a number of joins and windows, you should increase the JVM heap size for the workers.

1. Click the gear icon at the top right corner of the canvas to display the Application Configuration dialog.
2. Increase Number of Workers to 5.
3. Set Topology Worker JVM Options to -Xmx3072m.
