On behalf of the team and everyone who has contributed, I am pleased to announce the sixth and last milestone for the next Spring Data generation. This milestone continues delivering new features, refinements, and dependency upgrades.

Removed MongoDB UUID and BigDecimal Defaults

Spring Data MongoDB now aligns with the MongoDB Java Driver and no longer defaults to a representation for UUID values. Instead, you need to explicitly configure the desired representation through driver settings.

We're also no longer providing a default configuration value for BigInteger and resort the default for BigDecimal to Decimal128 in accordance with MongoDB's default codecs. This is a much safer approach that prevents you your application from accidentally switching representations when upgrading to the new major version. Please make sure to configure formats for big numbers through MongoCustomConversions…

On behalf of the team and everyone who has contributed, I am pleased to announce the fourth milestone for the next Spring Data generation. This milestone continues delivering new features, refinements, and dependency upgrades.

Updated MongoDB UUID Format Defaults

Spring Data MongoDB now defaults to the BSON binary subtype 4 to represent UUIDs migrating off the legacy subtype 3. While this change doesn't manifest in a breaking code change, any existing data stored in MongoDB using subtype 3 will not be read correctly and will either require migrating to BSON binary subtype 4 or switching the…

Ahead-of-Time Optimization for Repositories

When applying AOT optimizations through Spring Boot's build plugin, then AOT-generated Repositories are now enabled by default: You no longer need to set the spring.aot.repositories.enabled property. Additionally, you can disable AOT repository generation entirely or individually by setting either spring.aot.jpa.repositories.enabled=false or spring.aot.mongodb.repositories.enabled=false…

The emergence of Large Language Models (LLM) has propelled Generative AI and surfaced one of its key components to a broad audience: Embeddings.

Embeddings are a vector representation of data in a high-dimensional space capturing their semantic meaning. Vector representations allow for more efficient and effective search (Vector Search) of similar items. Vector search is typically used to build Retrieval-augmented generation (RAG) systems and so there is demand for vector databases.

While new vector databases are on the rise, existing database engines are gradually incorporating vector search…
