### CI Runners
-We use [Runs-On](https://runs-on.com/) for some actions in the main
repository, which run in the ASF AWS account to speed up CI time. In forks,
these actions run on the default GitHub runners since forks do not have access
to ASF infrastructure.
+#### Runs-On
+
+We use [Runs-On](https://runs-on.com/) for some actions in the main
repository, which run in the ASF AWS account to speed up CI. In forks, these
actions run on the default GitHub runners since forks do not have access to ASF
infrastructure.
+
+To configure them, we use the following format:
+
+`runs-on: ${{ github.repository_owner == 'apache' &&
format('runs-on={0},family=m8a,cpu=16,image=ubuntu24-full-x64,extras=s3-cache,disk=large,tag=datafusion',
github.run_id) || 'ubuntu-latest' }}`
+
+This is a conditional expression that uses Runs-On custom runners for the main
repository and falls back to the standard GitHub runners for forks. Runs-On
configuration follows the [Runs-On
pattern](https://runs-on.com/configuration/job-labels/).
+
+For those actions we also use the [Runs-On
action](https://runs-on.com/caching/magic-cache/#how-to-use), which adds
support for external caching and reports job metrics:
+
+`- uses: runs-on/action@cd2b598b0515d39d78c38a02d529db87d2196d1e`
+
+For the standard GitHub runners, this action will do nothing.
+
+##### Spot Instances
+
+By default, Runs-On actions run as [spot
instances](https://runs-on.com/configuration/spot-instances/), which means they
might occasionally be interrupted. In the CI you would see:
+
+```
+Error: The operation was canceled.
+```
+
+According to Runs-On, spot instance termination is extremely rare for
instances running for less than 1h. Those actions will be restarted
automatically.
+
+#### GitHub Runners
We also use standard GitHub runners for some actions in the main repository;
these are also runnable in forks.
