A fully managed and highly scalable data discovery and metadata management service.
New customers get $300 in free credits to spend on Google Cloud during the Free Trial. All customers get up to 1 MiB of business or ingested metadata storage and 1 million API calls, free of charge.
Simplifies data discovery at any scale
Empower any user on the team to find or tag data with a powerful UI, built with the same search technology as Gmail, or via API access. Data Catalog is fully managed, so you can start and scale effortlessly.
Overview of Data Catalog
Find out why you need a Data Catalog and how it powers the efficient use of your data.
Quickstart for tagging datasets
Make a BigQuery dataset, create a tag template with a schema, look up the Data Catalog entry for your table, and attach the tag to your table.
How to search with Data Catalog
Use Data Catalog to perform a search of data assets, such as datasets, tables, views, and Pub/Sub topics in your Google Cloud projects.
Restricting access with BigQuery column-level security
This page explains how to use BigQuery column-level security to restrict access to BigQuery data at the column level.
Access on-premises metadata connectors on GitHub
Commons code used by the Data Catalog connectors and links for the connectors sample code.
While you can use the Data Catalog API to create your own connectors for ingesting metadata from a data source of your choice, we provide you with “ready to use” open-source connectors for ingesting metadata from a number of common data sources like MySQL, PostgreSQL, Hive, Teradata, Oracle, SQL Server, Redshift, and more. Once in Data Catalog, all assets can be searched for and tagged.
Integrate your on-premises RDBMS metadata
Keep up with your on-premises Hive Server
The Data Catalog API can be used to ingest metadata from any business intelligence asset. For Looker and Tableau we have open-sourced ready-to-use connectors so they're discoverable and can be tagged directly in Data Catalog.
