Edge Run Request Generator

This project provides ready-to-use request generators that the Galileo project uses to generate workload (specifically, faas-sim and galileo-experiments)

The project is structured simply and offers multiple generators that produce inter-arrival times. Currently supported RPS profiles:

• Constant - does what you'd expect
• Sine - replicates a sine wave with a given peak (max rps) and period (simulation time in seconds between peaks)
• Randomwalk - creates a random walk pattern

RPS profiles yield a target average request per second pattern at a given time.

RPS profiles can be decorated using arrival profiles to get a more realistic request pattern. Following arrival profiles are supported:

• Static
• Expovariate

You can save profiles using the helper function save_requests and pre_recorded_profile to read a saved profile (only necessary if you like to plot it afterwards again).

Install

To install dependencies and develop, run:

make venv

This creates a virtual environment, activates it and installs all dependencies (requirements.txt and requirements-dev.txt).

If you like to run the notebooks (i.e., to generate request patterns and plot them comfortably):

pip install -e .
jupyter notebook

Note: you might have to restart the terminal session if jupyter notebook fails.
