How can I run multiple RSS triggers concurrently in n8n?

Below is some guidance:

Separate Workflows for Each RSS Trigger

n8n is designed so that each trigger node runs in its own execution context. When you put multiple RSS triggers in one workflow, they share a single execution context, which can lead to conflicts or missed events. The simplest way to run your RSS triggers in parallel is to move each one into its own workflow. Then, if needed, you can have those workflows pass their outputs (using Webhook, database write/read, or credentials) to a downstream combined workflow.

Considerations with Your Setup

• You’re running with SQLite and the default EXECUTIONS_PROCESS settings. While these work well for single workflows, SQLite may not be optimal for high-concurrency scenarios. For heavy parallel processing, consider using a database like Postgres and leveraging n8n’s queue mode (with separate worker processes) for better scalability.

• Running each RSS trigger in its own workflow minimizes potential conflicts and ensures that each feed is polled independently.

Summary

To set up multiple RSS triggers in parallel:

1. Create a separate workflow for each RSS trigger.
2. If you need to combine data or perform centralized processing, have each workflow export its output (e.g., via a webhook or shared datastore) to a common workflow.
3. Consider upgrading your database (SQLite → Postgres) and settings (using queue mode with workers) if you require higher levels of parallel processing and scalability.

This configuration will allow each RSS feed to be processed independently without interference from other triggers in the same workflow.
