Conversation
💡 **What:** The optimization removes per-step workflowRun updates during execution and batches all stepResults into memory to be saved in a single database update at the end of the workflow run (in the try and catch blocks). 🎯 **Why:** To solve the N+1 queries performance bottleneck. By accumulating step results in memory, the engine prevents unnecessary trips to the database for every single execution step. 📊 **Measured Improvement:** Execution time for a 1000-step workflow reduced from ~2377ms (1001 database updates) to ~147ms (1 database update).

There was a problem hiding this comment.
For long-running workflows that are interrupted outside the JS catch path (worker restart, SIGKILL, OOM) after one or more steps, this final-only stepResults write is never reached. Since the run is created with stepResults: {} and the per-step checkpoint was removed, persistent workflow history loses all completed step outputs; before this change the database retained progress after each loop iteration. Consider keeping an after-step or periodic checkpoint while still reducing write frequency.
