Pinterest replaces Kafka Streams with Apache Flink to run large-scale stream apps that power features for 478 million users, claiming reduced latency from hours to seconds by adding a Flink speed layer that buffers 24 hours (and seven days for some flows) and supports backfill/reprocess inside the app. Two engineers operate a stats pipeline launched to wide usage; shopping catalog updates go from 24 hours to 5 seconds, real-time conversion prediction improves attribution coverage, and matrix aggregation and A/B testing move from flaky to production-grade.
