+The :code:`client_name` is a user-defined string intended to give the client a unique identifier. You
 can provide the :code:`client_name` by passing it directly to the :ref:`ClientConfig <class_client_ClientConfig>` constructor.
 
 The Cognite API uses OpenID Connect (OIDC) to authenticate.

 Concurrency and connection pooling

 This library does not expose API limits to the user. If your request exceeds API limits, the SDK splits your
 request into chunks and performs the sub-requests in parallel. To control how many concurrent requests you send

 If you are working with multiple instances of :ref:`cognite_client:CogniteClient`, all instances will share the same connection pool.
 If you have several instances, you can increase the max connection pool size to reuse connections if you are performing a large amount of concurrent requests.
