Automated Workflow Orchestrator with Status Management
detail.loadingPreview
This n8n workflow intelligently manages the execution of other workflows, ensuring that only one instance runs at a time. It leverages Redis for real-time status tracking and a configurable schedule to prevent conflicts and optimize resource usage.
About This Workflow
This n8n workflow acts as a sophisticated guardian for your automated processes. It's designed to prevent redundant executions of critical workflows by checking their current status in Redis. Triggered on a defined schedule, it first queries Redis to see if a specific workflow is already running. If it is, the current execution is halted. If the workflow is idle, its status is updated to 'running', and then a designated sub-workflow is executed. Upon completion, the status is reset to 'idle' in Redis, allowing for subsequent executions. This robust mechanism ensures efficient resource utilization and prevents data corruption due to concurrent operations.
Key Features
- Intelligent Workflow Execution: Prevents concurrent runs of the same workflow using a dynamic Redis flag.
- Configurable Scheduling: Set custom intervals for workflow checks and executions.
- Real-time Status Monitoring: Utilizes Redis to maintain and query the 'running' or 'idle' status of workflows.
- Error Handling: Continues processing even if a sub-workflow encounters an error.
- Manual Reset Capability: Includes options for manual intervention to reset the workflow status to 'idle' if needed.
How To Use
- Configure Schedule Trigger: Define the
intervalin the 'Schedule Trigger' node to set how often the workflow should check for execution. For example, setsecondsIntervalto5for a 5-second check. - Set Workflow Status (Get): The 'Get Status' node uses a Redis key derived from the workflow ID (
workflowStatus_{{ $workflow.id }}) to fetch the current status. - Check Workflow Status (If): The 'Redis Key exists' node checks if the status flag retrieved from Redis is not empty. If it exists and is not 'idle', the workflow stops here.
- Continue if Idle (Filter): If the status flag is 'idle', the 'Continue if Idle' node allows the execution to proceed.
- Set Running Status: The 'Set Running' node updates the Redis flag to 'running', indicating that the workflow is now active.
- Execute Main Workflow: The 'Execute Workflow' node triggers the actual sub-workflow you want to run (specified by
workflowId). - Set Idle Status: After the sub-workflow completes (or if an error occurs), the 'Set Idle' node resets the Redis flag to 'idle'.
