TASK DESCRIPTION
these 2 queries were among the most expensive on datacenter failover or after it- while it is normal to have lower performance than usual due to colder caches, most likely they are surfacing issues with improvements. It would be nice to have some mitigation in place before the failback happens on the 3 May to avoid the issues mentioned on the parent ticket- even if it is as silly as reducing query batches:
