Class CouchbaseEmbeddingStore

java.lang.Object

dev.langchain4j.store.embedding.couchbase.CouchbaseEmbeddingStore

All Implemented Interfaces:

EmbeddingStore<TextSegment>

public class CouchbaseEmbeddingStore
extends Object
implements EmbeddingStore<TextSegment>

Represents a Couchbase index as an embedding store. Current implementation assumes the index uses the cosine distance metric.
Supports storing Metadata
