CREATE SETTINGS PROFILE

Creates settings profiles that can be assigned to a user or a role.

Syntax:

CREATE SETTINGS PROFILE [IF NOT EXISTS | OR REPLACE] name1 [, name2 [,...]] 
    [ON CLUSTER cluster_name]
    [IN access_storage_type]
    [SETTINGS variable [= value] [MIN [=] min_value] [MAX [=] max_value] [CONST|READONLY|WRITABLE|CHANGEABLE_IN_READONLY] | INHERIT 'profile_name'] [,...]
    [TO {{role1 | user1 [, role2 | user2 ...]} | NONE | ALL | ALL EXCEPT {role1 | user1 [, role2 | user2 ...]}}]

ON CLUSTER clause allows creating settings profiles on a cluster, see Distributed DDL.

Example

Create a user:

CREATE USER robin IDENTIFIED BY 'password';

Create the max_memory_usage_profile settings profile with value and constraints for the max_memory_usage setting and assign it to user robin:

CREATE
SETTINGS PROFILE max_memory_usage_profile SETTINGS max_memory_usage = 100000001 MIN 90000000 MAX 110000000
TO robin
