Metadata Labeling

Metadata management (MDM) can label all extracted metadata objects to support data analysis, search, and other extended functions.

Metadata Difference Comparison

MDM provides difference comparison of extracted metadata. Therefore, the lower-layer data source changes can be traced. This provides basis for subsequent data evolution analysis.

Backup and Restoration

MDM stores metadata in DBService, a reliable component of FusionInsight HD. The component does not have process data during running. Therefore, MDM ensures more reliable metadata backup and recovery based on the backup and restoration capabilities of DBService.
