Connection Pooling is a technique used in software applications to manage database connections efficiently. Instead of creating a new connection every time a request is made, a pool of pre-established connections is maintained. This allows applications to reuse existing connections, which saves time and resources, leading to faster response times and improved performance. When an application needs to access a database, it can quickly grab a connection from the pool rather than waiting for a new one to be created. Once the task is complete, the connection is returned to the pool for future use. This process helps optimize resource usage and enhances overall application efficiency.
