duraflows-persistence-adapter

To replace the default duraflows postgres persistence with Prisma or Drizzle, you implement custom adapters for three core interfaces: WorkflowInstanceStore, WorkflowHistoryStore, and WorkflowTransactionRunner, then wire them into the WorkflowModule runtime.

A persistence adapter in a workflow runtime is a custom implementation of storage and transaction interfaces that connects your database library to the workflow engine, preserving runtime guarantees like row-level locking and optimistic concurrency.

Yes, you can use TypeORM with duraflows for workflow instance storage by implementing the required WorkflowInstanceStore, WorkflowHistoryStore, and WorkflowTransactionRunner interfaces to bridge TypeORM into the workflow runtime.

You test a custom workflow persistence adapter for conformance by running the runInstanceStoreConformance test path, which validates that your implementation satisfies interface definitions, row-level locking, and optimistic concurrency requirements.

Yes, migrating workflow persistence layers requires handling transaction management manually within your adapter implementation, specifically by supplying a WorkflowTransactionRunner that satisfies the runtime's transaction and locking guarantees.
