Zero downtime Deployment on Kubernetes

on YouTube ↗37m

" summary

Shows a zero-downtime path that keeps a service live while changing a database schema: Kubernetes rolling upgrades plus a streaming pipeline that does initial bulk copy and then continuous replication of writes so new pods see up-to-date rows. Uses Hazelcast for the streaming job and session replication and a CDC connector (Debezium-style) to capture DB changes, with a Spring Boot app on the pods and a MySQL→Postgres-capable pipeline. Demo runs the forward job, migrates live writes, and the service stays up.
