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).
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.
