  "account": "Awaiting an external API inside a database transaction can lead to exhausting the connection pool in a Node.js backend handling database transactions alongside third-party API integrations. The architectural mistake of running an update, awaiting an external API call, and committing the transaction together creates bottlenecks. If the external service slows down or becomes unavailable, the transaction stays open, occupying connections for longer than necessary. This causes concurrent requests to wait in line for available connections, choking the whole system. To avoid connection pool bottlenecks, it is essential to decouple database writes from third-party services safely.",
