6.0.0-beta1 - Async Client, Filters, BM25 and FetchObjects Queries, API-Key Authorization

The first beta of client6 has arrived!

🔑 Use the new API Key authorization to securely connect to your Weaviate instance:

final var client = new WeaviateClient(
    Config.of("https", cfg -> cfg
        .httpHost("localhost").httpPort(443)
        .grpcHost("localhost").grpcPort(433)
        .authorization(Authorization.apiKey("my-api-key"))));

Similarly to Python and TS, client6 offers convenient helper .local() and .wcd() methods for connecting to you local instance or the one running in the Weaviate Cloud.

🔍 Search and retrieve objects using bm25 and fetchObjects queries:

final var books = client.collection.use("Books");

var crimeFiction = books.query.bm25("Sherlock Holmes", q -> q.queryProperties("main_character"));
var newestBooks = books.query.fetchObjects(
    query -> query
        .where(Where.property("yearPublished").gte(2024))
        .limit(200));

Explore other filters and query parameters by downloading the latest version from your local Maven Ce.....

💥 The first beta of client6 has arrived (asynchronously!!!) 💥

The Async Client presents the same familiar API. Its methods return an instance of CompletableFuture so they can be easily integrated with the existing processing pipelines. try it out!

// WeaviateClient and WeaviateClientAsync implement Closable
try (final var asyncClient = client.async()) {
    final var things = asyncClient.collections.use("Things");
    things.data.insert(Map.of("shape", "square"))
        .thenAccept(square -> System.out.println("square has id=" + square.metadata().uuid()));
}
