Why I'm doing

RuntimeFilterWorker may handle a delay runtime filter of a pre-maturely terminating query, so a query context is destructed before the using its query-level mem_tacker in RuntimeFilterWorker. when this mem_tracker is undergoing
desctruction, its parent mem_tracker (e.g. resource_group-level mem_tracker) would be accessed, however, the resource-group-level mem trackers has already been destructed when the resource group is dropped or altered.

Using query-level mem-tracker beyond query context's life time may lead to BE's crash as follows:

What I'm doing:

We need capture query context to prevent it from being destructed, and when a dropping resource_group is used by outstanding query contexts, it would be delayed to be dropped until all its outstanding query contexts are destructed.
