Send and Receive Messages Across Flows with Clear Control

With our Pub-Sub component, you can move data between flows in a simple and clear way. Because it follows the publish–subscribe pattern, you can send messages from one flow and let others react at once. Since you only need to set up a Topic that holds the data shape, both publishers and subscribers can use it on the elastic.io platform. Thus, your workflows stay light, fast, and easy to grow.

Key Benefits of Our Component

• Easy Topic Setup: Since you define a Topic once, all flows can start using it right away.
• Loose Coupling: Because each flow works on its own, you can change or scale it without trouble.
• Real-Time Work: As messages arrive, subscribers act at once, so your data moves smoothly.
• Flexible Flow Design: Since each subscriber reads only what it needs, your logic stays simple.

Popular Use Cases

Here are a few ways you can benefit from using the Pub-Sub component:

• News Alerts: After you publish new data, one flow can send emails through the Email connector.
• Data Syncing: When a system adds fresh records, another flow can store them in Google Sheets.
• File Archiving: As events come in, a flow can store them as files with the SFTP connector.

Because it reacts fast, connects well, and stays easy to adjust, our Pub-Sub component helps you build smooth and stable event-based flows.
