Guides

Persistence

Since workflows are typically long running processes, they will need to be persisted to storage between steps. There are several persistence providers available as seperate npm packages.

Multi-node clusters

By default, the WorkflowHost service will run as a single node using the built-in queue and locking providers for a single node configuration. Should you wish to run a multi-node cluster, you will need to configure an external queueing mechanism and a distributed lock manager to co-ordinate the cluster. These are the providers that are currently available.
