Claim: capture database writes and stream them into specialized stores so each service gets the view it needs. Implements change data capture using Red Hat’s Debezium → Kafka, then materializes into MongoDB (10-node cluster), Neo4j and Elasticsearch via Kafka Streams, demonstrating denormalized movie documents and graph queries that work. Kafka sustains millions of messages/sec and lets systems rebuild state from the log; joins require local state stores and rebuilding half‑a‑billion rows can take hours. This is an event-driven microservices approach with eventual consistency and replayable data.
