This release of the Cloudera Data Warehouse (CDW) service on CDP Public Cloud has the following behavior changes:

Change in Grafana metrics collection
Before this release:
Many metrics for Grafana monitoring were being stored for 45 days without limits on the disk space consumed. Resource overruns could occur and impact the availability of the entire environment.
After this release:

Storing metrics longer than 15 days or consuming more than 90GB of disk space is not supported. Metrics older than 15 days will be deleted. If the stored metrics consume more than 90GB of disk space, metrics will be deleted regardless of the number of days stored.
