Run Cache: Automatic Log of Stage Runs

Every time you run a pipeline with DVC, it logs the unique signature of each stage run (in .dvc/cache/runs). If it never happened before, its command(s) are executed normally. Every subsequent time a stage runs under the same conditions, the previous results can be restored instantly — without wasting time or computing resources. More details

✅ This built-in feature is called run cache and it can dramatically improve performance. It's enabled out-of-the-box (can be disabled), which means DVC is already saving all of your tests and experiment results behind the scene.

The run cache is also enabled when you use dvc exp run (see DVC Experiments).
