StateMachineInstall

Summary

Checks whether a Redis key exists and returns the result in each output item’s json.state field. The key is global by default; disable Global Statement to scope it to the current workflow.

Inputs

• Value (required) — Key value to check. The node hashes it to form a workflow-scoped Redis key; for global state, the source uses a shared key.
• Global Statement — Defaults to true. When false, scopes the key to the current workflow.
• Redis credentials (required) — Connection settings for the Redis database, including host, port, database, and optional password.

Output shape

One output item per input item, each with json.state set to a boolean.

true means Redis reports the key exists; false means it does not. The operation connects to Redis and does not modify the key.
