Key Considerations for Acquiring a Database Connection

What is Connection Pooling?

Connection pooling is a technique used to manage a pool of database connections that can be reused, rather than creating a new connection for every database request. By reusing connections, connection pooling reduces the overhead of creating and tearing down connections, which can improve application performance. Connection pooling is particularly useful in environments where the cost of establishing a new connection is high, such as when using SSL/TLS for encryption. The pool manager monitors the pool for idle connections and reuses them when possible, reducing the need to create new connections. If no idle connections are available, the pool manager can create a new connection, up to a configurable maximum limit, to meet the demand....

How Does Connection Pooling Works?

The inner workings of connection pooling are straightforward which following sequence of operations:...

Key Considerations for Acquiring a Database Connection

Now, let’s understand the connection pooling. But first, let’s understand the steps involved in establishing a database connection. Opening a connection is not just a simple task. It involves several operations, such as:...

Integrating a Connection Pooler: Different Approaches

Built-in Support: Many ORMs come with built-in support for connection pooling. Using the built-in mechanism is the simplest way to get started. External Pooling Libraries: For ORMs that do not support pooling or if we require more advanced features, we can use external libraries like HikariCP (for Java) or PGBouncer (for PostgreSQL databases). Database-Side Pooling: Some databases offer their connection pooling capabilities. While this is not directly related to ORM, it can be a complementary strategy....

What are the Effects of Increasing Connections on Database Server?

In terms of resources, the impact that the connections count on the database server could not be ignored. As more and more database servers become a source of connection, to the same extend they will be required to address the constrained quantity of the resources. Some of the key resource implications include:...

How does the Number of Connections Affect Client Applications?

The implications of the same connection count carry further than the machine where database server resides and create a stealth effect on the client app as well. Consider the following implications:...

What are Some Common External Connection Poolers?

A plethora of external connection pooling solutions abound, catering to diverse programming ecosystems and database platforms. Among the most prominent exemplars are:...

Difference Between Internal and External Pooling

Connection pooling manifests in two distinct incarnations, each characterized by its modality of deployment and management:...

Conclusion

In the world of software engineering, making sure that applications run fast and can handle a lot of users at the same time is super important. That’s where something called ORM connection pooling comes in. It’s basically a way to manage how your application talks to the database efficiently....
