How to Minimise the Impact of Database Latency

Minimizing database latency is crucial for enhancing the performance of applications, and the Neon Regional Latency Dashboard offers a valuable tool for developers to measure and manage this aspect. The dashboard provides latency benchmarks between popular hosting providers and Neon regions, helping teams identify optimal deployment locations. By optimizing code, queries, and database connection management, developers can mitigate the impact of latency on application response times. Techniques such as addressing the N+1 problem, batching queries, leveraging Postgres features like RETURNING and ON CONFLICT clauses, reusing database connections, and employing application-level connection pooling can significantly reduce latency-related delays. These strategies collectively enhance application responsiveness, particularly in serverless environments where persistent connections aren't feasible. By placing backends closer to databases and minimizing round trips, developers can ensure snappier API response times, ultimately leading to more efficient and scalable applications.
