Metadata Collection
DAS periodically collects the metadata of DB instance databases, tables, and fields and stores the collected data in the DAS database.

When determining whether to deploy resources in the same AZ, consider your applications' requirements on disaster recovery (DR) and network latency.
- For robust DR, deploy clusters in different AZs within the same region.
- For lower network latency, deploy resources in the same AZ.
