In this article, we will deal with the definition of indexes in Spring Data JPA and the Hibernate Framework. Our focus is on defining an index for a non-primary key and using the @Index annotation. The proper use of indexes plays a crucial role in optimizing the performance of your database, as they enable faster data queries and overall improve database performance. Defining an Index with the @Index Annotation With JPA and Hibernate, you can define indexes on entities and non-entity tables such as @SecondaryTable, @CollectionTable, and @JoinTable using the @Index annotation.

Laziness Prevails

Hi, Laziness prevails. Always. Countless times I’ve tried to adopt beneficial routines. I joined a gym - after a few months, I barely went anymore. I baked my own bread - after (admittedly) two years, I no longer did. I got up at 5 am to meditate and exercise - I couldn’t maintain this for more than 4 weeks. As good as these routines would have been, had I kept them up for years - they come with high investments.

It was not my intention at all to provide valuable, SEO optimized content that helps random visitors to the site. No. It was there for two things.
