/** 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.
|
|
* More rich and efficient, but less compatible
|
|
* - data is transferred by columns;
|
|
* - data is transferred compressed;
|
|
* Allows to get more information in response.
|
|
* 3. Interserver HTTP - for replication.
