[BohuTANG]

Summary

For some cases, user uses a databend-query server as a proxy and do multi-tenant operations in a same session, for example:

sudo use tenant  'id1';
create user xx...;
create database 'xx';
sudo use tenant  'id2';
create database 'yy';

Goals:
Make databend-query as a proxy, users can do some meta operations(database/table/users/stage creating) from the databend-query for different tenants.
