FUNCTIONAL EVENT-DRIVEN ARCHITECTURE

on YouTube ↗31m

" summary

A concise preview of a Scala 3 book that shows concrete patterns and runnable code rather than theory: examples use Apache Pulsar (Kafka-compatible) plus Cats Effect and FS2 to implement simple event processing and stateful CEP via a finite state machine driven by FS2’s evalMapAccumulate and merged tick streams, a Postgres-backed outbox pattern shipped via CDC connectors (Pulsar IO / Debezium) to guarantee delivery, demos of Pulsar subscription types and ephemeral WebSocket subscriptions that ran in production, and a 97-stargazer raffle run from the repo.
