cross-posted from: https://programming.dev/post/19544005 > When managing a database, speed and efficiency are crucial. As applications handle more data and become more complex, the performance of database queries plays a big role in keeping everything running smoothly. One of the best ways to make queries faster is by using indexes. Similar to a book’s index that helps you quickly find a topic, database indexes allow you to find specific data without searching through the entire database. This article explains the basics of indexing, how it improves query performance, and some simple tips for using indexes effectively. Whether your database is small or large, understanding how to use indexes can help keep your application fast and responsive.

Hey, thanks for your comment:) it was mentioned that these are opinions of experienced Java developers not based on research.
LadyLeeLoosh 6mo ago • 80%
appreciate your feedback. Do you have any tips?
digma.ai
Tips for becoming a better Java developer, including upgrading Java versions, learning Kotlin, exploring other languages/frameworks, understanding Loom and Structured Concurrency, getting coverage from Oracle, learning Groovy and Scala, practicing Continuous Feedback, using Ktor, building side projects, focusing on observability, staying connected with the Java community, reading professional developer blogs, following influencers on social media, and signing up for a Java articles reading list.
When discussing Observability, OpenTelemetry is crucial because it enables organizations to understand the internal state of their systems through telemetry data. In this article, we will discuss the important role of OpenTelemetry in enabling Observability in Java applications.
