In these cases, developers use different tools and techniques to identify the bug or error in…
Even if you write clean, efficient, readable code and have good coverage of your code with unit test cases, it is impossible to write once and run it all the time perfectly. In most cases, bugs are inevitable, and debugging is part of the daily life of a developer. Therefore, learning debugging tricks will improve…

Implementing caching for AWS sessions is crucial to improve performance, achieved by minimizing configuration loading. After migrating to Spring Boot, I utilized Spring Cache abstraction while retaining the Google Guava Expiring HashMap. The cache can be enabled with the `@EnableCaching` annotation and configured using Spring’s annotations. The setup includes a custom `CacheConfiguration` class and caching behavior annotations on service methods, such as IamClient. Future migration to Redis is considered, and code examples are available on my GitHub repository.
