New and Noteworthy

Spring Data Commons - 3.5

Mark pure Repository SpEL Components for Removal

After introducing support for Value Expressions, we now no longer require components that only support SpEL without following the newly introduced Value Expressions API. Therefore, we’re deprecating QueryMethodEvaluationContextProvider (and its reactive variants), and SpelEvaluator for removal in the next major release.

Please migrate off this API towards their Value Expression replacements.

Spring Data for Apache Cassandra - 4.5

Upgrade to Cassandra 5

We’ve upgraded the Cassandra driver to version 4.19 and we’re building against Cassandra 5.0.

Support for Storage-Attached Indexes

Spring Data Cassandra ships with support for Storage-Attached Indexes. Specifically, we provide programmatic interfaces to specify and generate CQL for CREATE INDEX … USING 'sai' and the @SaiIndexed annotation for text and vector index definitions.

Vector Search support

With introducing the Spring Data Vector type, we now allow using vector data types in mapped entities. We support both, Cassandra’s CqlVector and our Vector type to insert and query for vector data. Cassandra uses vectors in queries for similarity and ordering.

@Table
class CommentSearch {

	String comment;

	float similarity;
}

@Table
class Comments {

	@Id UUID id;
	String comment;

	@VectorType(dimensions = 5)
	@SaiIndexed Vector vector;
}

Vector vector = Vector.of(/* from your Embedding */);
Columns columns = Columns.empty().include("comment").select("vector",
		it -> it.similarity(vector).cosine().as("similarity"));
Query query = Query.select(columns).limit(3).sort(VectorSort.ann("vector", vector));

List<CommentSearch> result = template.query(Comments.class).as(CommentSearch.class).matching(query).all();

Spring Data Redis - 3.5

Spring Data KeyValue - 3.5

Support for `Not`, `NotIn`, and `NotLike` query keywords

Map-based repositories now support Not, NotIn, and NotLike keywords when using query derivation.

interface PersonRepository extends Repository<Person, String> {

  Person findByFirstnameNot(String firstname);

  Person findByFirstnameNotLike(String firstname);

  Person findByFirstnameNotIn(List<String> in);
}
