Vector Stores

Lyzr supports multiple vector databases for knowledge base storage. You bring your own credentials for most; Weaviate and Qdrant are available with Lyzr’s default credentials for quick setup.

​

Supported vector stores

The vector store is selected when you create a Knowledge Base. You can’t change the store after creation — create a new KB if you need to migrate.

​

Configuring credentials

Go to Data Connectors → Create New → select the vector store type → enter credentials. Credentials are stored encrypted and scoped to your organization.

​

Choosing a vector store

For most use cases, Qdrant (fast, free default credentials, good performance at scale) is the right starting point. Use Neo4J when building a Knowledge Graph.
Use SingleStore if you’re already running SingleStore for operational data.
Use PG Vector if you want vector storage inside your existing PostgreSQL instance.
