URL shortener written in golang.
redis is used to store the shortened URLs.
It is an URL shortener. It is a service you can use to shorten your URLs. Similar to services like bit.ly and bl.ink.
It is just an experiment, a toy project to learn and exercise my systems design skills. I want this project to be:
- Fast
- Testable
- Deployable
- Debuggable
go get -u github.com/mauricioabreu/shortify
There is support for docker-compose:
docker-compose up
Now you can run the server and use the service:
shortify
Shortening an URL:
curl -sv https://localhost:8000/ -XPOST -d "url=https://www.maugzoide.com/"
Retrieving the URL:
curl -sv https://localhost:8000/d41d8cda2f -XGET
go test -v ./...
One of the premises of this service is to be fast. To show how fast this service is, we need to benchmark the service running. We run the server and use a tool to perform a load testing, sending multiple HTTP requests as if it is facing a high number of people using it.
This report uses the hey tool. It is a replacement for Apache Benchmark.
What are we going to measure:
- Latency - how fast a server responds to the requests in the load test. HTTP requests are a bit
- Throughput - how many requests the server can succesfully respond in a specific interval.
Computer specs for this benchmark:
- Intel Core i7, 2.2 GHz
- 6 GB ram
- Ubuntu 16.04 (xenial)
