      Description

      Advanced performance optimizations and tuning of the shared scans. This includes:

      • Reschedule user queries on a different scheduler. Two possible parts to this are detecting slow queries and moving them to a slower/lower priority scan scheduler and the other would be having the czar tell the workers to move all tasks for a user query to a specific scheduler. These require unique user query ids.
