Java application performance tuning using Lightrun

Introduction In this article, I’m going to show you analyze a Java application using Lightrun so that you can discover various performance tuning improvements you could apply to your current Java application. In this previous article, I explained what Lightrun is and how you can use it to inject dynamic logs, capture runtime snapshots, or add dynamic metrics. In this article, I’m going to use Lightrun as an alternative to my JPA Association Fetching Validator.

JPA Association Fetching Validator

Introduction In this article, I’m going to show you how we can build a JPA Association Fetching Validator that asserts whether JPA and Hibernate associations are fetched using joins or secondary queries.

Keyset Pagination with Spring

Introduction In this article, I’m going to show you how you can use the Keyset Pagination technique with Spring or Spring Boot. While the default offset-based pagination provided by Spring Data PagingAndSortingRepository is useful in many situations, if you have a large result set that you have to iterate over, then the Keyset Pagination or Seek Method technique provides better performance.
