Requirements

Functional Requirements:

Capacity Estimation

100rps

API Design

User login register logout to make the links

POST /link/

GET /link/{link}

High-Level Design

We have microservices a user service using which the user logs in with its own db

then a link service where the user can make a link or get the original long link

when making a short link a worker uses outbox pattern to send a message to a consumer and a consumer get that link and shortlink combination and writes it to the db

then a replicated readonly db coppies the write and a user using cache writethrough can get the original link

Database Design

i use sql because the data is structured and its engough for the task at hand?

Detailed Component Design

i already explained it in high level design, do i have to do that again here?
