Summary

When starting databend-query with ./databend-query --dynamic-cluster -c ./databend-query.toml, databend-query will be added to the resource pool of the corresponding tenant and reject all SQL requests except for CREATE DYNAMIC CLUSTER, DROP DYNAMIC CLUSTER, and SHOW DYNAMIC CLUSTERS.

When a user executes CREATE DYNAMIC CLUSTER xx WITH NODES = XX, it will obtain the corresponding number of nodes from the tenant's resource pool to form a new cluster.

When a user executes DROP DYNAMIC CLUSTER xx, all nodes of the corresponding cluster will be destroyed and returned to the tenant's resource pool.

Dynamic clusters and non-dynamic clusters cannot form the same cluster.
