Why do databases use Connection Pooling? Connection Pooling - A technique where a pool of pre-established database connections is maintained and reused by applications, instead of creating and closing a new connection for every request, improving performance and resource efficiency. Why databases use it: - Creating a database connection is expensive (authentication, network setup, resource allocation). - Reusing existing connections reduces latency and CPU overhead. - Limits the number of simultaneous connections to protect the database. - Improves throughput in high-traffic systems. How it works: Application requests connection → Pool provides an existing connection → Query executes → Connection returns to pool Example: - A web application receives 1,000 requests per second. - Without pooling: 1,000 new connections created each second. - With pooling: A fixed pool (e.g., 50 connections) handles all requests efficiently. Fewer connections created.More requests handled. Better performance. #Database #ConnectionPooling #SystemDesign #Backend #Performance #TechBasics

実際F/O対策で苦しんでる現場は大量にあって、AWS公式も対応方法を記事化してるし、そんな状況下で「F/Oに対する強みこそが、RDS Proxyの強み」だと思うのですが、これから使う組には、Tomcat＋ConnectionPooling時代にやってた設定、どうすればいいの？設定ないけどどう動くの？が結構重要かなと。

お役に立てて光栄です。当然といえば当然ですがRDS Proxyやっぱり微妙にベンチスコア落ちますよね。私も手元で同じことを試してました。あとは従来のConnectionPooling（Tomcat＋Tomcat JDBC ConnectionPooling）でできる設定との違いとか、ちょっと調べてる途中です。

R1D16: Another day without an actual commit. *sigh* Spent a lot of time reading and learning about using DataSource and ConnectionPooling. I'm going to need some more time to wrap my brain around that. Starting to feel the #100DaysOfCode initial excitement wear off. #KeepPushing
