Does ClickHouse support local node execution switching?

[0xfei]

Does ClickHouse support local node execution switching on distributed query execution? This would prevent a slow query on one node from slowing down the entire query, just like use_hedged_requests

No. ClickHouse can't change the number of nodes dynamically during query execution. It is either fully local of fully distributed with the number of nodes based on the statically defined cluster topology.
