When should I use Amundsen instead of PACE?

Data discovery and metadata catalog with a search-first UI and social features like table popularity. Organizations wanting a Lyft-style data catalog with usage signals and human-curated descriptions. Teams needing a graph-backed metadata store with Neptune or Atlas as the metadata backend

When should I use PACE instead of Amundsen?

Automated data privacy and compliance policy enforcement at the data platform level. Teams needing GDPR and CCPA access controls enforced automatically without manual policy management. Organizations wanting policy-as-code that generates data access controls from a central definition

What are the main weaknesses of Amundsen?

Complex multi-component deployment: metadata service, search service, and frontend all required. Requires significant engineering effort to maintain connectors and keep metadata fresh. Smaller default connector set than DataHub; custom connectors require more implementation work

What are the main weaknesses of PACE?

Very new and niche tool with limited production adoption and few public case studies. Tightly coupled to specific data platforms; integration breadth is still limited. Requires existing mature data platform infrastructure to operate effectively

How Python Data Engineers Use These Tools

Amundsen

Python data engineers use Amundsen's databuilder library to write custom extractor jobs that pull metadata from internal databases and push it to Amundsen's index. Engineers also use the Amundsen API to programmatically tag datasets with ownership, freshness SLAs, and quality tier labels that the search UI surfaces to data consumers.

PACE

Python data engineers use PACE to enforce data privacy policies on pipeline outputs — defining masking rules for PII columns and row-level security filters in code. Python scripts call the PACE API to deploy policies after new warehouse tables are created, ensuring sensitive data is automatically protected before stakeholders access it via BI tools or SQL clients.
