¿Qué es una conexión pool?

A connection pool is a technique to optimize the management of database connections. Instead of establishing a new connection each time, a connection is requested from the existing pool, saving time and resources.

1. Performance improvement: By reusing existing connections instead of establishing a new one each time, the cost of connection establishment is avoided, resulting in improved application performance.
2. Resource savings: By using a connection pool, excessive consumption of computational resources is avoided by reducing the burden of repeatedly establishing and closing connections.
3. Faster response time: By having pre-established and available connections in the pool, requests can be serviced more quickly, resulting in improved application response time.
4. Connection control and management: A connection pool allows for more efficient control over the maximum number of connections allowed, thus avoiding database or server overload.
5. Scalability: By using a connection pool, the application can efficiently handle a greater number of concurrent requests without saturating the available resources, which facilitates the scalability of the application.
