  /** Server provides three interfaces:
    * 1. HTTP - simple interface for any applications.
    * 2. TCP - interface for native clickhouse-client and for server to server internal communications.

    *     - data is transferred by columns;
    *     - data is transferred compressed;
    *    Allows to get more information in response.
    * 3. Interserver HTTP - for replication.
