# The Problem

Pulumi saves snapshots at every deployment step to maintain data integrity. For large stacks, this creates a bottleneck: uploading the full snapshot serially slows everything down.

Instead of sending the whole snapshot, journaling sends only individual changes. These journal entries can go in parallel, and Pulumi Cloud reconstructs the full snapshot on the backend.
