What is lookup enrichment in data pipelines?
Why copied rows still miss business context, where lookup enrichment belongs, and how to think about joins before target write.
Guides
Technical notes for teams building enriched operational data pipelines.
Readable engineering guides on the problems that appear after raw replication works: missing context, lookup joins, target contracts, pipeline validation, PII, and operational recovery.
