> Since Ignite 2.12 java thin client always connects to the first address from the provided address list. In typical configuration this leads to overloading an one server node and underloading other server nodes. 
> To improve workload distribution we can:
>  # Choose random first channel from the range of addresses with the same (minimal) port.
>  # If partition awareness is enabled use random open channel instead of default channel for operations which can't be mapped to a certain node.
