Amazon Managed Service for Prometheus now supports out of order sample ingestion

Amazon Managed Service for Prometheus now supports out-of-order sample ingestion and a workspace-level rule query offset. All workspaces have a default out-of-order time window of 1 minute, allowing the workspace to accept metric samples arriving outside strict chronological order. You can adjust this window to match your ingestion patterns or set it to 0 to disable the feature and discard out-of-order samples. You can also configure a global rule query offset that introduces a delay before rule evaluation queries run, giving late-arriving samples time to be ingested before rules execute. Toge
