Interfaces

ClickHouse provides two network interfaces (both can be optionally wrapped in TLS for additional security):

• HTTP, which is documented and easy to use directly.
• Native TCP, which has less overhead.

In most cases it is recommended to use appropriate tool or library instead of interacting with those directly. Officially supported by Yandex are the following:

• Command-line client
• JDBC driver
• ODBC driver
• C++ client library

There are also a wide range of third-party libraries for working with ClickHouse:

• Client libraries
• Integrations
• Visual interfaces
