Description

As reported:

If I do an aggregation over a large time span, the searchers will end up being killed by kubernetes for missing health checks. I'd assume because the CPU usage is too high and they are mostly un-responsive

Research direction

Start by reproducing an aggregation over a large time span and observe the searchers' Kubernetes health checks and CPU usage. Trace the searcher path responsible for the unresponsive health checks; done means expensive aggregations no longer cause searchers to be killed for missing health checks.
