Distributed Transactions in Service Mesh

on YouTube ↗35m

" summary

Shows a concrete implementation of the distributed saga pattern using Istio and Envoy filters: a Lua Istio envoy filter records transaction IDs to a Propeller service which writes state to a three‑node Hazelcast cluster, and on an HTTP 500 from the banking service the filter invokes stored compensation actions to undo product stock and user credit updates. Demo uses three replicas for Propeller and Hazelcast, demonstrates automatic rollback after an injected bank failure, and explains orchestration via filters rather than XA two‑phase commit.
