Boost query performance by more than 2.5X and reduce storage costs by 50% compared to self-tuned Hive tables, without lifting a finger. Many data teams still need to manually develop and schedule custom tasks to maintain each and every table in their lakehouse, leading to inconsistent query performance and runaway costs.

Hyperlinks connect users to pages, actions, and content. In web testing, they are everywhere. That’s why knowing how to click a hyperlink in Selenium WebDriver is one of the first and most essential skills for any test automation engineer. Selenium makes it simple, but real-world links come with variations. Some are plain anchor tags. Some use JavaScript. Others open new tabs or redirect dynamically. Each requires a slightly different approach.

Generative AI copilots are moving from experimental tools to core enterprise solutions. But too often, organizations rush into development, only to discover adoption stalls because the copilot doesn’t solve a specific user problem, lacks trust safeguards, or can’t scale reliably. This guide lays out best practices across the entire lifecycle, from planning and building, to deployment, monitoring, and long-term maintenance.

A couple of weeks ago, our team returned from API World. We’ve officially had a few weeks to decompress and get back into the swing of things after an incredible time at API World 2025. Looking back, the experience was even more rewarding than I had imagined in my Pre-API World blog. This year was especially memorable for me, as I had the opportunity to attend my first tech conference and travel across the country for work. I’m still buzzing from everything I learned and the people I met.

Analyzing performance test results has long been one of the most complex and time‑consuming aspects of performance engineering. As the volume of testing increases and delivery cycles continue to accelerate, teams face mounting challenges in making sense of vast amounts of data.

Ruby has a robust error handling mechanism called rescue. The way it works is the keyword rescue specifies an exception handler that will catch and handle any exceptions that are raised in the begin block, the code block preceding the rescue block that may cause an exception. Here’s how it looks: When an exception occurs in the begin code block, Ruby transfers control to the rescue block and executes the code within it.

InvocationTargetException is a confusing error message that Java developers often encounter. The good news?
