ASF GitHub Bot updated FLINK-21865:
-----------------------------------
Labels: pull-request-available (was: )
> Add a Docker Compose greeter example to StateFun playgrounds
> ------------------------------------------------------------
>
> Key: FLINK-21865
> URL: https://issues.apache.org/jira/browse/FLINK-21865
> Project: Flink
> Issue Type: Task
> Components: Stateful Functions
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
> Priority: Major
> Labels: pull-request-available
> Fix For: statefun-3.0.0
>
>
> This example is intended as a follow-up after completion of the Java SDK
> Showcase Tutorial (FLINK-21862).
> If users are already familiar with the Java SDK fundamentals and would like
> to get a better understanding of how a realistic StateFun application looks
> like, then this would be the example they start with. Otherwise, we would
> recommend users to take a look at the Showcase tutorial first.
> This example works with Docker Compose, and runs a few services that build up
> an end-to-end StateFun application:
> - Functions service that runs functions and expose them through an HTTP
> endpoint.
> - StateFun runtime processes (a manager plus workers) that will handle
> ingress, egress, and inter-function messages as well as function state
> storage in a consistent and fault-tolerant manner.
> - Apache Kafka broker for the application ingress and egress.
> To motivate this example, we'll implement a simple user greeter application,
> which has two functions - a {{UserFn}} that expects {{UserLogin}} JSON events
> from an ingress and keeps in state storage information about users, and a
> {{GreetingsFn}} that accepts user information to generate personalized
> greeting messages that are sent to users via an egress.
