6.2.0 - Server-Side Batching, Proxy, multi2multivec-weaviate, Drop Vector Index, Query Profiling

The new version brings support for a number of features introduced in Weaviate v1.36 and v1.37.

SSB

We are happy to announce that weaviate-java-client now features a client for the new Server-Side Batching protocol.

List<WeaviateObject<Map<String, Object>>> myObjects;
try (BatchContext<Map<String, Object>> batch = client.batch.start()) {
    myObjects.forEach(batch::add);
} catch (InterruptedException e) { /* BatchContext is interruptible.  */ }

Proxy

Thanks to @fer-marino it is now possible to proxy your Weaviate connection and OIDC token-exchange requests.

Proxy proxy = new Proxy(
    /* scheme */ "https",
    /* host */ "example.com",
    /* port */ 4505,
    /* username */ "john_doe",
    /* password */ "pa$$w0rd");
WeaviateClient.connectToLocal(conn -> conn.proxy(proxy));

Third-party modules

The list of supported modules now includes multi2multivec-weaviate vectorizer.
The multi2vec-google module now also supports audio modality.

And more!

6.0.0-M2 - Generative Search, RBAC, Multi-Target Queries, Vectorizer Modules, Backups

With this release we consider the client to be generally feature-complete and ready for productive usage.
Compared to v5, this client only lacks the Batch API, which will be added as soon as Server-Side Dynamic Batching obtains the GA status.

In this iteration we've added support for a whole host of new features:

1. All vectorizer, generative, and reranker modules available in Weaviate as of v1.33 are available in client6 (except for the deprecated ones)
2. Generative search and Dynamic RAG
3. Support for multiple query targets in query, aggregate, and generate namespaces
4. Backups, Replication, and Cluster+Nodes APIs
5. Nested objects, PhoneNumber, and GeoCoordinates data types
6. Filtered pagination!
7. Many smaller improvements to align with other client libraries

Got no plans this weekend? Update your pom.xml / build.gradle to use 6.0.0-M2 and have a go at the new APIs!
