Prototype - link shortener

Problem statement

There is a need for training in optimizing Go applications. So I decided to create an application that will have:

1. Non-trivial business logic
2. Accessing the database/other services

That's all the requirements.
Considering the limitations and my needs, two projects come to mind: a link shortener and my own disk.
+ I have a Raspberry Pi5 with a Samsung 500GB SSD 980 series lying around, on which they could be deployed.

The first implementation in line will be the link shortener.

Project requirements

General requirements (+ must be in MVP):

1. Have a simple authorization and registration tool.
2. +When the user clicks on an abbreviated link, transfer him to the resource.
3. +Store links for the necessary time (indefinitely)

Performance requirements:

1. RPS > 10k
2. The ability to store up to 10e9 links
3. Service availability 0.99

Hardware:

1. Raspberry Pi5 8gb + SSD m2 Samsung 980 500GB
2. Radxa Rock 4a + SSD m2 A DATA xpg 128GB
3. HP Mini PC 800 g1(I'll describe the details later)

Commit design style

• feature - used when adding new application-level functionality
• fix - if you fixed some serious bug
• docs - everything related
• to the style documentation - correcting typos, correcting
• refactor formatting - refactoring the application code
• test - everything related to testing
• chore - routine code maintenance

Style: action (with a small letter) + for which entity + (optional details)

Example: fix NoMethodError in RemoteReader
