After the refactoring on both client and server side, we should have the ability to fully use lance REST namespace to call into LanceDB cloud and enterprise. We can avoid having a JNI implementation (which today does not really do anything except for vending a connection object), and just use lance-core's RestNamespace. We will at this moment have a LanceDbRestNamespaceBuilder to allow users to more easily build the RestNamespace to talk to LanceDB Cloud or Enterprise endpoint. In the future, we could extend this further to also support the local mode through DirectoryNamespace. That will be a separated PR.
LanceDB Java SDK
Configuration and Initialization
LanceDB Cloud
For LanceDB Cloud, use the simplified builder API:
import com.lancedb.LanceDbRestNamespaceBuilder;
import org.lance.namespace.RestNamespace;
// If your DB url is db://example-db, then your database here is example-db
RestNamespace namespace = LanceDbRestNamespaceBuilder.newBuilder()
.apiKey("your_lancedb_cloud_api_key")
.database("your_database_name")
.build();
LanceDB Enterprise
For Enterprise deployments, use your custom endpoint:
RestNamespace namespace = LanceDbRestNamespaceBuilder.newBuilder()
.apiKey("your_lancedb_enterprise_api_key")
.database("your_database_name")
.endpoint("<your_enterprise_endpoint>")
.build();
