PolarDB for PostgreSQL lets you archive cold data from your cluster to an Object Storage Service (OSS) bucket to reduce your data storage costs. After you enable cold data tiering and perform cold data archiving, OSS charges are based on the storage capacity the archived data occupies.
For an overview of cold data tiering, see Overview of cold data tiering.
