Redis Node

What it does​

Executes Redis operations such as get/set/del against a configured Redis instance for caching and lightweight state.

Inputs/config​

  • Redis credential reference.
  • Command/operation type.
  • Key, value, and optional TTL/expiration.

Outputs/branches​

  • Uses matched_output.
  • success on command success.
  • error on connectivity/auth/command failures.

Example usage snippet​

{
  "id": "n_redis",
  "type": "redis_node",
  "config": {
    "operation": "set",
    "key": "order:{{input.id}}",
    "value": "{{input}}",
    "ttl_seconds": 300
  }
}

Common pitfalls​

  • Forgetting TTL and accumulating stale cache keys.
  • Storing oversized payloads instead of compact cache objects.
  • Assuming Redis write succeeded without handling error branch.
