**What are Production rules?**\
\
In Google Cloud Platform (GCP), **production rules** often refer to configurations or policies applied in services like Cloud Firestore or BigQuery to manage data and operations in a production environment. For instance, in Firestore, production rules might define security rules for data access and validation. In BigQuery, they could involve data retention policies and query execution settings. Essentially, production rules help ensure that services are secure, efficient, and adhere to operational standards in a live, production environment.
