In single-region buckets, a large fraction of the data has been deleted via gsutil rm. When viewing the Google Cloud Platform > Monitoring > Metrics Explorer, with Resource: GCS Bucket Metric: Total bytes Group By: bucket_name, the metrics have not seen a decrease after 6 hours.
The monitoring of requests definitely shows the expected activity at the time the delete was requested, and the files are no longer visible via either gsutil or the GCP > Cloud Storage > Browser.
Is there an expected delay in full deletion, or in the monitoring of this metric?
The monitoring data is only updated once per day [doc].
