What is database connection pooling in Java microservices?

What is database connection pooling in Java microservices?

Database connection pooling is a technique used to manage database connections efficiently in Java microservices. It allows multiple requests to share a pool of connections, reducing the overhead of creating and closing connections repeatedly.

Why is connection pooling important for microservices?

Connection pooling is crucial for microservices because it enhances performance by minimizing latency and resource consumption. It allows services to handle more requests simultaneously without overwhelming the database.

How do I implement connection pooling in a Java microservice?

You can implement connection pooling in a Java microservice using libraries like HikariCP or Apache DBCP. These libraries provide configuration options to set the maximum pool size, connection timeout, and other parameters.

What are the common issues with connection pooling?

Common issues include connection leaks, where connections are not returned to the pool, and exhaustion of the connection pool, which can lead to performance bottlenecks.
