FaaSNet

FaaSNet is the first system that provides an end-to-end, integrated solution for FaaS-optimized container runtime provisioning. FaaSNet uses lightweight, decentralized, and adaptive Function Trees (FTs) to avoid major platform bottlenecks.

This repo contains two components:

• A FaaS cold start trace dataset collected from Alibaba Cloud Function Compute.
• The source code of the function tree prototype of FaaSNet.

The Function Cold Start Traces from Alibaba Cloud Function Compute

Introduction

Our trace dataset is a subset of the data described in, and analyzed, in our ATC '21 paper. The traces were obtained by collecting 24-hour production-level logs from two datacenters (Beijing and Shanghai) in Alibaba Function Compute service during May 2021.

Using the Data

License

The data is made available and licensed under an Apache License 2.0. By downloading it or using them, you agree to the terms of this license.

Dataset Downloading

We would like you could help us take the survey before downloading the FaaS cold start traces. The link is as following Google Form, you could retrieve the download link after submmting the form successfully.

Please free to let us know if you have any further questions.

Schema and Description

Field	Description
__time__	TimeStamp in seconds
functionName	Unique id for the function name
latency	Function cold start latency1 in seconds
runtime	Function runtime (Python, nodejs, custom-runtime, etc)
memoryMB	Function's allocated memory in MB

Notes:

1. The function cold start latency only counts the system level's latency, such as container initialization, etc, instead of end-to-end cold start latency.

Function Tree Prototype

Our released function tree (FT) prototype is the version that we evaluated in the ATC '21 paper. We are continuing to improve the performance of it. We're happy to accept contributions! Please feel free to hack on the FT and integrate it into your framework/platform :-).
