Bumping max_overflow increases the maximum concurrent DB connections per service instance from 7 to 10 (pool_size + max_overflow). If Cloud Run concurrency or other workloads can spike, this may increase pressure on the Cloud SQL connection limit. Consider making pool sizing configurable via environment (or documenting the expected per-instance connection budget) to avoid surprises in production.
