[Description of problem] In the prometheus pod logs it's possible to read errors processing load dues too many examples into memory in query execution the message: ~~~ 2020-10-12T08:18:00.703972307Z level=warn ts=2020-10-12T08:18:00.703Z caller=manager.go:525 component="rule manager" group=kube-apiserver-availability.rules msg="Evaluating rule failed" rule="record: apiserver_request:availability30d\nexpr: 1 - ((sum(increase(apiserver_request_duration_seconds_count{verb=~\"POST|PUT|PATCH|DELETE\"}[30d]))\n - sum(increase(apiserver_request_duration_seconds_bucket{le=\"1\",verb=~\"POST|PUT|PATCH|DELETE\"}[30d])))\n + (sum(increase(apiserver_request_duration_seconds_count{verb=~\"LIST|GET\"}[30d]))\n - (sum(increase(apiserver_request_duration_seconds_bucket{le=\"0.1\",scope=~\"resource|\",verb=~\"LIST|GET\"}[30d]))\n + sum(increase(apiserver_request_duration_seconds_bucket{le=\"0.5\",scope=\"namespace\",verb=~\"LIST|GET\"}[30d]))\n + sum(increase(apiserver_request_duration_seconds_bucket{le=\"5\",scope=\"cluster\",verb=~\"LIST|GET\"}[30d]))))\n + sum(code:apiserver_request_total:increase30d{code=~\"5..\"} or vector(0))) / sum(code:apiserver_request_total:increase30d)\nlabels:\n verb: all\n" err="query processing would load too many samples into memory in query execution" 2020-10-12T08:21:00.851730908Z level=warn ts=2020-10-12T08:21:00.851Z caller=manager.go:525 component="rule manager" group=kube-apiserver-availability.rules msg="Evaluating rule failed" rule="record: apiserver_request:availability30d\nexpr: 1 - ((sum(increase(apiserver_request_duration_seconds_count{verb=~\"POST|PUT|PATCH|DELETE\"}[30d]))\n - sum(increase(apiserver_request_duration_seconds_bucket{le=\"1\",verb=~\"POST|PUT|PATCH|DELETE\"}[30d])))\n + (sum(increase(apiserver_request_duration_seconds_count{verb=~\"LIST|GET\"}[30d]))\n - (sum(increase(apiserver_request_duration_seconds_bucket{le=\"0.1\",scope=~\"resource|\",verb=~\"LIST|GET\"}[30d]))\n + sum(increase(apiserver_request_duration_seconds_bucket{le=\"0.5\",scope=\"namespace\",verb=~\"LIST|GET\"}[30d]))\n + sum(increase(apiserver_request_duration_seconds_bucket{le=\"5\",scope=\"cluster\",verb=~\"LIST|GET\"}[30d]))))\n + sum(code:apiserver_request_total:increase30d{code=~\"5..\"} or vector(0))) / sum(code:apiserver_request_total:increase30d)\nlabels:\n verb: all\n" err="query processing would load too many samples into memory in query execution" ~~~ In this error is possible to see that this query is delivered by default with the default configuration for prometheus. [Version-Release number of selected component (if applicable)] How reproducible: Steps to Reproduce: 1. Install OCP 4.5 2. Enabled techPreviewUserWorkload 3. Check prometheus pod logs after some time [Actual results] Possible to read the error mentioned above [Expected results] The errors are not shown and it's possible to execute the query without any issues
