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…

There are a few features we want to highlight for you to explore:

• Interface Projections using now are guarded properly throwing NullPointerException if a method return value is null (i.e. a getter method) although the method is defined to return a non-nullable value. This functionality is enabled for all Kotlin Interfaces. For all other interfaces, validation is enabled when the package or the interface is annotated with Nullability annotations and marked as non-null (or inherits @NonNullApi from the package level).
• Hash Field Expiration for Spring Data Redis, extended Expiration command support, and support for GET … SET.
• ValidatingEntityCallback and a reactive variant ReactiveValidatingEntityCallback…
