Dapr Workflow Testing

Important

This repo is purely for load testing Dapr Workflows runtime. It is not an example of what good looks like! Most of the code is junk, to meet the end goal of testing the Workflows Runtime.

In the past, this has flushed out many concurrency issues in the underlying durabletask-go library, which have been subsequently addressed in newer versions of the Dapr runtime.

The dapr runtime version for all compose files is specified in the .env file.

---

Run with 5 instances of the Workflow App, and 3 instances of the scheduler service

1. docker compose -f compose-5-3.yml build
2. docker compose -f compose-5-3.yml up

Run a simple monitor pattern workflow

This will create many workflow instances randomly distributed across the Workflow App instances.

Run the workflows by making a POST request to :

http://localhost:5112/start/monitor-workflow?runId={runId}&count=1000&async=true

• Where {runId} is a unique value i.e. UUID/GUID.
• Increase/decrease the amount of workflows created by changing the count property

Run a simple fan-out & fan-in pattern workflow

This will create many workflow instances randomly distributed across the Workflow App instances.

Run the workflows by making a POST request to :

http://localhost:5112/start/fanout-workflow?runId={runId}&count=1000&async=true

• Where {runId} is a unique value i.e. UUID/GUID.
• Increase/decrease the amount of workflows created by changing the count property
