Spring Data MongoDB - Relation Modelling

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 when the need occurs to work with relations.

Spring Data 2020.0 - New and Noteworthy in Spring Data MongoDB 3.1

The Spring Data MongoDB 3.1 release is one of the modules that highly benefited from the recent changes in the Spring Data Commons module, by leveraging the infrastructure built there to bring reactive features like auditing and SpEL. The following snippet gives you an impression of what this means for declarative MongoDB queries using SpEL:

@Query("{ 'supervisor' : ?#{ hasRole('ROLE_ADMIN') " +
  "? new Document('$regex', '*') : principal.name } }")
Flux<Person> findAllFilteredByRole();

@EnableReactiveMongoAuditing uses the common infrastructure so you can keep track of changes easily.
