Prevent Concurrent Workflow Runs in n8n

# Prevent concurrent n8n workflows using Redis lock

This automation template solves the problem of multiple simultaneous executions of the same workflow in n8n, which can lead to conflicts, duplicated operations, or system overload. Using Redis as a distributed state store, the locking mechanism ensures that only one instance of a process runs at any given time.

## Who it´s for
- n8n developers building long-running or critical processes
- System architects designing reliable automation systems
- DevOps teams using n8n in production environments

## What the automation does
- Accepts internal calls from other workflows via executeWorkflowTrigger
- Performs actions: get status, set lock, unset lock
- Uses Redis keys to track execution state
- Ensures no duplicate run starts while the previous one is active
- Allows external systems to query current process status (e.g., ´started´, ´loading´, ´finishing´)

## What´s included
- Ready-to-use n8n workflow with Redis integration
- Trigger and handler logic for state management
- Integrations only with Redis and n8n´s internal API
- Basic text instructions for setup and adaptation

## Requirements for setup
- Active n8n environment with access to internal workflow triggers
- Access to a Redis server (local or cloud)
- Configured environment variables for Redis connection

## Benefits and outcomes
- Prevents race conditions and execution conflicts
- Ensures data integrity during long processes
- Avoids server overload from duplicate tasks
- Simplifies scaling of automations in production
- Increases reliability of critical business workflows
- Enables external monitoring of process status
