Abstract base class for persistent key-value stores.

Stores enable persistence and memory that can be shared across threads, scoped to user IDs, assistant IDs, or other arbitrary namespaces.

Features:

  • Hierarchical namespaces for organization
  • Key-value storage with metadata
  • Vector similarity search (if configured)
  • Filtering and pagination

Delete an item from the store.

Retrieve a single item by its namespace and key.

List and filter namespaces in the store. Used to explore data organization and navigate the namespace hierarchy.

Store or update an item.

Search for items within a namespace prefix. Supports both metadata filtering and vector similarity search.

Start the store. Override if initialization is needed.

Stop the store. Override if cleanup is needed.
