+## Database
+
+Redash uses CrunchyDB for its highly available database.
+
+```sh
+helm -n a12c97-tools upgrade --install crunchy-tools-redash ../crunchydb/charts/tools -f crunchydb-tools-values.yaml
+helm -n a12c97-tools upgrade --install crunchy-postgres-redash ../crunchydb/charts/crunchy-postgres -f crunchydb-postgres-values-no-limits.yaml -f crunchydb-postgres-values.yaml
+```
