Node categories in this workflow

  • Trigger
  • Routing
  • Subworkflow
  • Data store
  • Transform
  • Wait

Icons describe general node roles, inferred from node types. Inspect the parameters for the configured action.

Drag to pan; use + and − to zoom. Reconstructed from the exported node positions; nothing runs here. Dashed lines represent non-main connections. Full node names and notes appear below.

How it works

The exported workflow contains the following configured nodes. Their connections are shown above; inspect the JSON for the complete logic, expressions, and external actions.

Setup

  1. Download the JSON and import it into an isolated n8n instance. Leave the workflow inactive.
  2. Connect your own credentials through n8n’s credential store. Replace REPLACE_WITH_* values with your resource identifiers.
  3. Inspect API destinations, Code nodes, database queries, file paths, and outbound actions.
  4. Run with synthetic data and harmless destinations. Enable triggers only after checking the actual outputs.

Requirements

An n8n instance with the listed node types and compatible versions. Service-connected workflows may require accounts, credentials, or paid APIs.

Credential types declared in the source

  • redis

Workflow notes

Check if working

Check if working

Will output status if something is going on.

Inputs:

  • action -> "get"
  • key -> a string used for tracking
  • Remove unused inputs when calling workflow *
Set workflow start

Set workflow start

Inputs:

  • action -> "set"
  • key -> a string used for tracking
  • value -> "working" by default but you can use whatever, you can use this multiple times in combination with get to track progress of a execution.
  • Remove unused inputs when calling workflow *
Set workflow end

Set workflow end

This mark workflow end by unsetting the key.

Inputs:

  • action -> "unset"
  • key -> a string used for tracking
  • Remove unused inputs when calling workflow *
Redis logic

Redis logic

Modify Set Timeout to adjust timeout (in seconds)

Your logic that takes time

Your logic that takes time

If a process is ran at the same moment, it will raise a error

Purpose and structure

This folder contains the Prevent concurrent workflow runs using Redis workflow. Its executable nodes use executeWorkflow, executeWorkflowTrigger, if, manualTrigger, noOp, redis, set, stopAndError, switch, wait. The table and connection map below are derived from the JSON, not an inferred guarantee of behavior.

Setup

Import inactive. Configure your own credentials and replace REPLACE_WITH_* values. Review external destinations and Code nodes before running.
