Since its inception, Spring Data Repositories have been designed for extension, whether you want to customize a single query method or provide a completely new base implementation.

The 2024.1 release enhances your ability to extend a repository with custom functionality making it easier than ever for anyone to create extensions that can be shared across different projects.

Let’s explore an example to see how this works in practice.

Imagine you are using MongoDB as a document store to manage a movie database. You want to leverage MongoDBs Atlas vector search functionality through your…

MongoDB’s flexible schema allows for multiple patterns when it comes to modeling relationships between entities. Also, for many use cases, a denormalized data model (storing related data right within a single document) might be the best choice, because all information is kept in one place, so that the application requires fewer queries to fetch all data. However, this approach also has its downsides, such as potential data duplication, larger documents, and the maximum document size.

In general, MongoDB recommends using normalized data models when the advantages of embedding are neglected by the implications of duplication. In this blog post, we take a look at the different possibilities of linking documents with manual references and DBRefs…
