As stated already, connections and their creation are not free. In PostgreSQL, we have to fork an entire process to create a connection. In case a connection lives for a very long time, this is no problem. However, forking a process for just a very short query can be really expensive....
PgBouncer is a lightweight PostgreSQL connection pooler that improves database performance and scalability by managing client connections efficiently. It helps reduce the overhead of frequently opening and closing connections, making it ideal for high-traffic applications. 1. Why use PgBouncer? Reduces c...
PostgreSQL is “The World’s Most Advanced Open Source Database,” and I believe it. In my 10+ years of working with it, it’s been solid, serving up data to SaaS loads of over 1000 queries per second, rarely going down, surviving all manner of accusations of corruption (...

PostgreSQL 数据库是采用的进程模型,因此每个连接都会对应一个后端进程,该后端进程将分配系统资源(例如内存,work_mem),大量的空闲会话将导致内存无法得到有效的使用,有了空闲会话超时功能我们可以设置超时时间来避免空闲会话占用系统资源。 实现 该功能的实现与 ...
durid连接postgresql durid连接池 connection closed 轻车熟路,连接归还是通过Connection的代理对象重写close方法完成的,通过前面的学习我们已经知道Connectin的代理对象是DruidPooledConnection,所以我们直接看DruidPooledConnection的close方法。 ### DruidPooledConnection#close ...
