dapr-workflow-examples

This repo is for load testing Dapr Workflows via Docker Compose.

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. main currently targets 1.14.x of the runtime which is the first version to address the horizontal scaling constraints by inclusion of the new Actor Reminder sub-system.

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

1. docker compose -f compose-5-instances-3-schedulers.yml build
2. docker compose -f compose-5-instances-3-schedulers.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
