List Stores

The ListStores request retrieves a list of all vector stores available on the Ahnlich DB server.

• Input: No arguments required.

• Behavior: The server returns information about all existing stores including their names, dimensions, and indices.

• Response: A list of StoreInfo objects containing store metadata.

  const response = await client.listStores(new ListStores());

  // Get store names

  // Iterate over stores with full details

    console.log(`  Entries: ${store.len}`);

StoreInfo Fields

Each StoreInfo object contains:

Field	Type	Description
name	string	The name of the store
dimension	number	Vector dimension for this store
len	number	Number of entries in the store
sizeInBytes	bigint	Total size of the store in bytes
predicateIndices	string[]	List of indexed predicate keys
nonLinearIndices	NonLinearAlgorithm[]	List of non-linear indices (KDTree, HNSW)
