 In the case of using **multiple instances** of `TarantoolClient` we strongly recommend to apply a **shuffle** function to the list of addresses.
 By default, `TarantoolClient` uses the [round-robin](https://en.wikipedia.org/wiki/Round-robin_scheduling) approach for selecting the next available connection to distribute the load between Tarantool servers.
 When several instances of `TarantoolClient` are used simultaneously, with the default connection selection strategy and without **shuffling** of the server addresses the first request from every instance will be sent to the same server.
