In case you have different roles for the same user on multiple clusters,
ON CLUSTER query can help to overcome some limitations.
Consider the following example:
- cluster_with_data, dev_user (readonly=2)
- stage_cluster, dev_user (readonly=0)
So when you will execute the following query from stage_cluster, it will
be successfully executed, since ON CLUSTER queries has different system
profile:
DROP DATABASE default ON CLUSTER cluster_with_data
This is not 100% safe, but at least something.
Note, that right now only ON CLUSTER query it self is supported, but
separate clusters are not (i.e. GRANT CLUSTER some_cluster_name TO
default), since right now grants sticked to database+.

ClickHouse configs for test environment
How to use
CI use these configs in all checks installing them with install.sh script. If you want to run all tests from tests/queries/0_stateless and test/queries/1_stateful on your local machine you have to set up configs from this directory for your clickhouse-server. The most simple way is to install them using install.sh script. Other option is just copy files into your clickhouse config directory.
How to add new config
Just place file .xml with new config into appropriate directory and add ln command into install.sh script. After that CI will use this config in all tests runs.
