Required memory

Fact 29

9:42 shard-keeper page and i'm still in it. think i finally have the stupid diff -- label-name change from earlier made it into shard-keeper, never got picked up by rollup-service, so all the symptom alerts went off and none of the cause ones did. INC-2023-04-18-001 already has my name all over it i guess. haven't paged Hema yet. if this rollback behaves maybe 20 min, but the path is fragile and i do not want to widen this at 11:45 for no reason. looks like sev2, probably lands around ~5h45m by the time it's actually clean. impaired ingestion basically the whole window. i don't think we lost data. just... great.

Fact 30

Alex Valdez believed INC-2023-04-18-001 was caused by an earlier label-name change reaching shard-keeper but not rollup-service, which triggered all symptom alerts and no cause alerts.
