SystemDesigns TinyUrl KGS Service

Key Generation Service (KGS) that generates random six letter strings beforehand and stores them in a database

Building jar file

To generate the app.jar file it's necessary to have docker installed in your machine

./gradlew build

This task will up the redis docker database, execute all tests and build the app.jar inside build/lib folder

Run

To run KGS through Gradle you can execute the task but before remember to have docker dependencies up and running so:

docker-compose up -d
./gradlew bootRun

In bootstrap KGS will generate all possible keys of length 3 (not six, for save time and space) and store them in redis.

API

You can get keys doing POST request to localhost:8080/keys_request endpoint with body:

{
	"quantity": 10
}

And you will get as response:

[
    "tQiR",
    "sbGH",
    "sUs9",
    "s6U2",
    "tty1",
    "tA62",
    "ttP6",
    "tdoy",
    "sygH",
    "sSDW"
]

Dockerfile

You can build and image from KGS or use it from another project with

docker run --network=host victuxbb/tinyurlkgs 

Keep in mind that KGS is pointing to a REDIS in localhost machine, this is enought for this POC.
