ComfyUI-WorkflowCheckpointing

Automatically creates checkpoints during workflow execution. If If an workflow is canceled or ComfyUI crashes mid-execution, then these checkpoints are used when the workflow is re-queued to resume execution with minimal progress loss.

Configuration

By default, checkpoints are saved localy to a checkpoint folder.

Networked checkpoints backed by the Salad Simple Storage Service can be enabled by setting the SALAD_ORGANIZATION environment variable. When deployed to salad, authentication is automatically pulled, but an api key can be applied when testing locally by setting SALAD_API_KEY

If a request sent to /prompt contains a client_id. It is utilized to allow independent caching of executions by multiple users.

To facilitate testing FORCE_CRASH_AT can be set to an integer to terminate workflow execution at a given sampling step
