A live Flink SQL demo rebuilds community stats by ingesting GitHub commits, PRs and three mailing‑list mbox archives into Kafka then querying them from the Verica platform editor and a session Flink cluster. Queries use tumbling 30‑day windows and distinct counts to produce monthly metrics: distinct mailing‑list users, total emails, and threads (average ~4.0 emails per thread). The Chinese user list shows higher volume; the dev list query runs as a retract stream and writes top committers into Elasticsearch (top anonymous/hidden email 160 commits, next 32 and 16).
