What is connection pooling in microservices?

What is connection pooling in microservices?

Connection pooling is a technique used to manage database connections efficiently in microservices. It allows multiple requests to share a limited number of database connections, reducing the overhead of establishing new connections.

Why is connection pooling important for microservices?

It's important because it improves performance by minimizing the time spent on connection management, reduces resource consumption, and enhances scalability by allowing more requests to be handled simultaneously.

How do I implement connection pooling in my microservices architecture?

You can implement connection pooling by using libraries or frameworks that support it, such as HikariCP for Java or pg-pool for Node.js. Configure the pool size and other parameters based on your application's needs.

What are the common pitfalls of connection pooling?

Common pitfalls include misconfiguring the pool size, leading to either resource exhaustion or underutilization, and not handling connection leaks properly, which can degrade performance over time.
