Restate is a system for easily building resilient applications, workflows, asynchronous tasks, and event-driven applications.

This example contains the code for the Tour of Restate tutorial, for the Python API. This tutorial takes your through key Restate features by developing an end-to-end ticketing app.

To set up the example, use the following sequence of commands.

Setup the virtual env:

python3 -m venv .venv
source .venv/bin/activate

Install the requirements:

pip install -r requirements.txt

Start the app as follows:

python -m hypercorn --config hypercorn-config.toml tour/app/app:app

Start the Restate Server (other options here):

restate-server

Register the service:

restate deployments register http://localhost:9080

Then add a ticket to Mary's cart:

curl localhost:8080/CartObject/Mary/addTicket -H 'content-type: application/json' -d '"seat2B"'

Let Mary buy the ticket via:

curl -X POST localhost:8080/CartObject/Mary/checkout

That's it! We managed to run the example, add a ticket to the user session cart, and buy it!
