Pinterest Automates Schema Evolution Across Kafka, Flink, Spark, Iceberg
Pinterest’s CDC ingestion platform now auto‑propagates schema changes through Kafka, Flink, Spark and Iceberg, turning schema into a contract rather than metadata. The system generates code and metadata artifacts, handles both push‑ and pull‑based migrations, and audits updates via PRs, cutting manual drift and keeping online/offline data consistent.
