Only SQL: Empower data analysts end-to-end with Flink SQL
summary
Demonstrates that non-programmers can build end-to-end streaming workflows using only Flink SQL: reads clickstream and speech data from Kafka (Confluent REST proxy), parses a cookie via regex to extract an identifier, uses a 10‑second tumble window to emit users with ≥3 home-page views, inserts triggers into Elasticsearch for on-site notifications, and performs a temporal join with a text‑to‑speech topic to show a “how to contribute” alert when a simulated call happens within 10 seconds. The live demo runs and shows notifications appearing in the browser.
