Paper Moon: A Comparison of Stateful Functions and Pulsar Functions

on YouTube ↗36m

" summary

Compares Flink Stateful Functions vs Pulsar Functions by concrete tradeoffs: Stateful Functions uses Flink for durable state with checkpointing/snapshotting, offers key/value state via SDKs (Java, Python, Go) plus REST-style serving and broad ingress/egress support; Pulsar Functions runs against Pulsar brokers/BookKeeper, processes topic-to-topic flows, is lightweight on K8s and exposes per-topic state and counters via BookKeeper and a new Function Mesh for orchestration. Conclusion: chose Stateful Functions for wider state/serving ecosystem.
