## Common use cases
### Restore-only caches
If there are several builds on the same repo it might make sense to create a cache in one build and use it in the
others. The action [actions/cache/restore](https://github.com/actions/cache/blob/main/restore/README.md#only-restore-cache)
should be used in this case.
### Automatically detect cached paths
[Defining outputs for jobs](https://docs.github.com/en/actions/using-jobs/defining-outputs-for-jobs) can be used to
automatically detect paths to cache and use them to configure `actions/cache` action.
```yaml
- name: Get Go cached paths
id: find-cached-paths
run: |
echo "cache=$(go env GOCACHE)" >> $GITHUB_ENV
echo "modcache=$(go env GOMODCACHE)" >> $GITHUB_ENV
- name: Set up cache
uses: actions/cache@v3
needs: find-cached-paths
with:
path: |
${{ env.cache }}
${{ env.modcache }}
key: setup-go-${{ runner.os }}-go-${{ hashFiles('go.sum go.mod') }}
restore-keys: |
setup-go-${{ runner.os }}-go-
```

## Force deletion of caches overriding default cache eviction policy
Caches have [branch scope restriction](https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows#restrictions-for-accessing-a-cache) in place. This means that if caches for a specific branch are using a lot of storage quota, it may result into more frequently used caches from `default` branch getting thrashed. For example, if there are many pull requests happening on a repo and are creating caches, these cannot be used in default branch scope but will still occupy a lot of space till they get cleaned up by [eviction policy](https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows#usage-limits-and-eviction-policy). But sometime we want to clean them up on a faster cadence so as to ensure default branch is not thrashing. In order to achieve this, [gh-actions-cache cli](https://github.com/actions/gh-actions-cache/) can be used to delete caches for specific branches.

This workflow uses `gh-actions-cache` to delete all the caches created by a branch.
