Package dyntabs.ai.rag

Class MilvusConfig

java.lang.Object

dyntabs.ai.rag.MilvusConfig

public final class MilvusConfig
extends Object

Immutable connection settings for a Milvus vector database collection.

Analogy: think of MilvusConfig as a JDBC connection URL — but for vectors instead of rows. Just as jdbc:postgresql://host:5432/mydb tells JDBC where the table lives, a MilvusConfig tells EasyAI where the embedding collection lives (host, port, collection) plus the one extra thing vectors need that SQL tables don't: the embedding dimension().

Used by both the ingestion side (EasyAI.indexer()) and the retrieval side (AssistantBuilder.withMilvus(MilvusConfig)), so a single MilvusConfig can describe "where the vectors live" for the whole round trip.

Create explicitly

 MilvusConfig cfg = MilvusConfig.of("localhost", 19530, "documents");
 

Or read from easyai.properties

 easyai.milvus.host=localhost
 easyai.milvus.port=19530
 easyai.milvus.collection=documents
 easyai.milvus.dimension=384
 

 MilvusConfig cfg = MilvusConfig.fromProperties();
 

The default dimension() is 384, matching the local embedding model bundled with the langchain4j-easy-rag module (and the widely used all-MiniLM-L6-v2). If you embed with a different model, set the matching dimension or Milvus will reject the inserts.

of

public static MilvusConfig of(String host,
 int port,

Convenience factory for the common case: host, port, and collection name, with the default embedding dimension().

Parameters:

host - Milvus server hostname

port - Milvus server port (typically 19530)

collectionName - the target collection

Returns:

a new MilvusConfig

fromProperties

public static MilvusConfig fromProperties()

Loads Milvus settings from easyai.properties on the classpath.

Recognised keys: easyai.milvus.host, easyai.milvus.port, easyai.milvus.collection, easyai.milvus.dimension, easyai.milvus.username, easyai.milvus.password.

Returns:

a MilvusConfig populated from the properties file (with defaults applied)
