--- title: Vector Stores | Developer Documentation --- Vector stores contain embedding vectors of ingested document chunks (and sometimes the document chunks as well). ## Simple Vector Store By default, LlamaIndex uses a simple in-memory vector store that’s great for quick experimentation. They can be persisted to (and loaded from) disk by calling `vector_store.persist()` (and `SimpleVectorStore.from_persist_path(...)` respectively). ## Vector Store Options & Feature Support LlamaIndex supports over 20 different vector store options. We are actively adding more integrations and improving feature coverage for each. | Vector Store | Type | Metadata Filtering | Hybrid Search | Delete | Store Documents | Async | | -------------------------- | ----------------------- | ------------------ | ------------- | ------ | --------------- | ------------------------------ | | Alibaba Cloud OpenSearch | cloud | ✓ | | ✓ | ✓ | ✓ | | Apache Cassandra® | self-hosted / cloud | ✓ | | ✓ | ✓ | | | Astra DB | cloud | ✓ | | ✓ | ✓ | | | Azure AI Search | cloud | ✓ | ✓ | ✓ | ✓ | | | Azure CosmosDB Mongo vCore | cloud | | | ✓ | ✓ | | | Azure CosmosDB NoSql | cloud | | | ✓ | ✓ | | | BaiduVectorDB | cloud | ✓ | ✓ | | ✓ | | | ChatGPT Retrieval Plugin | aggregator | | | ✓ | ✓ | | | Chroma | self-hosted | ✓ | | ✓ | ✓ | | | Couchbase | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | | | DashVector | cloud | ✓ | ✓ | ✓ | ✓ | | | Databricks | cloud | ✓ | | ✓ | ✓ | | | Deeplake | self-hosted / cloud | ✓ | | ✓ | ✓ | | | DocArray | aggregator | ✓ | | ✓ | ✓ | | | DuckDB | in-memory / self-hosted | ✓ | | ✓ | ✓ | | | DynamoDB | cloud | | | ✓ | | | | Elasticsearch | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | ✓ | | FAISS | in-memory | | | | | | | Google AlloyDB | cloud | ✓ | | ✓ | ✓ | ✓ | | Google Cloud SQL Postgres | cloud | ✓ | | ✓ | ✓ | ✓ | | Hnswlib | in-memory | | | | | | | txtai | in-memory | | | | | | | Jaguar | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | | | LanceDB | cloud | ✓ | | ✓ | ✓ | | | Lantern | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | ✓ | | MongoDB Atlas | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | | | MyScale | cloud | ✓ | ✓ | ✓ | ✓ | | | Milvus / Zilliz | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | | | Neo4jVector | self-hosted / cloud | ✓ | | ✓ | ✓ | | | OpenSearch | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | ✓ | | Pinecone | cloud | ✓ | ✓ | ✓ | ✓ | | | Postgres | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | ✓ | | pgvecto.rs | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | | | Qdrant | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | ✓ | | Redis | self-hosted / cloud | ✓ | | ✓ | ✓ | | | S3 | cloud | ✓ | | ✓ | ✓ | ✓\* (using asyncio.to\_thread) | | Simple | in-memory | ✓ | | ✓ | | | | SingleStore | self-hosted / cloud | ✓ | | ✓ | ✓ | | | Supabase | self-hosted / cloud | ✓ | | ✓ | ✓ | | | Tablestore | cloud | ✓ | ✓ | ✓ | ✓ | | | Tair | cloud | ✓ | | ✓ | ✓ | | | TiDB | cloud | ✓ | | ✓ | ✓ | | | TencentVectorDB | cloud | ✓ | ✓ | ✓ | ✓ | | | Timescale | | ✓ | | ✓ | ✓ | ✓ | | Typesense | self-hosted / cloud | ✓ | | ✓ | ✓ | | | Upstash | cloud | | | | ✓ | | | VectorX DB | cloud | ✓ | ✓ | ✓ | ✓ | ✓ | | Vearch | self-hosted | ✓ | | ✓ | ✓ | | | Vespa | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | | | Vertex AI Vector Search | cloud | ✓ | | ✓ | ✓ | | | Weaviate | self-hosted / cloud | ✓ | ✓ | ✓ | ✓ | | | WordLift | cloud | ✓ | ✓ | ✓ | ✓ | ✓ | For more details, see [Vector Store Integrations](/python/framework/community/integrations/vector_stores/index.md). ## Example Notebooks -
