List Stores

Description​

ListStores returns the set of vector stores currently available on the Ahnlich DB server. Use it to discover what stores exist and to validate that a target store is present before you attempt writes or similarity queries.

Behavior​

  • The call returns a collection of store identifiers from the server at the time of the request.

  • Treat the result as an enumeration: don’t assume ordering or uniqueness semantics beyond what the server provides.

  • An empty list simply means no stores are present yet on that server.

if err != nil {
return nil, fmt.Errorf("failed to dial DB server %q: %w", ServerAddr, err)
}
client := dbsvc.NewDBServiceClient(conn)
return &ExampleDBClient{conn: conn, client: client, ctx: ctx}, nil
}


func (c *ExampleDBClient) Close() error { return c.conn.Close() }


// InfoServer example
func (c *ExampleDBClient) exampleInfoServer() error {
resp, err := c.client.InfoServer(c.ctx, &dbquery.InfoServer{})
if err != nil {
return err
}
fmt.Println("InfoServer:", resp)
return nil
}


func main() {
ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
defer cancel()


client, err := NewDBClient(ctx)
if err != nil {
log.Fatalf("Failed to create DB client: %v", err)
}
defer client.Close()


if err := client.exampleInfoServer(); err != nil {
log.Fatalf("InfoServer failed: %v", err)
}
}

This method sends a ListStores request and prints the returned set of stores via resp.Stores. If the RPC fails, the returned error indicates the call did not succeed.
