Google Cloud Knowledge Catalog

Google Cloud Knowledge Catalog is a web-based, cloud-deployed service for discovering data and managing metadata. Standard processing includes data discovery and automatic metadata discovery from Cloud Storage. Premium processing adds data lineage, data quality, data profiling and a data exploration workbench. Lineage options include column-level, pipeline and report lineage, while impact analysis helps trace relationships among data assets. Automated discovery is also available. Billing is divided among processing, metadata storage, API calls and shuffle storage, with separate descriptions for each category. Standard and premium processing and shuffle storage are pay-as-you-go; no prices are listed. The Free tier covers the first 100 DCU-hours per month for standard processing, the first 1 million API calls per month, and 1 MiB of metadata storage. The overall pricing model is paid, and there is no free plan. Google was founded in 1998 and is headquartered in Mountain View, California, USA.

Knowledge Catalog brings discovery, metadata and lineage functions together in a cloud service. Its listed free allowances apply to specific usage categories, while the overall model is paid.

It may suit organizations looking for cloud-based data discovery, metadata management and lineage capabilities. Teams should account for its separate billing categories and the lack of a free plan.
