Url shortener service

Technologies:

• Go
• Grpc
• Postgres
• Redis

Featres:

• Clean architecture
• Concurrency safe
• Low latency
• Cache
• Default BASE62 algorithm
• Customizable algorithm
• Multiple algorithms support

Services:

• Link Service
• Key Generation Service
• Algorithm Factory
• Number Service

Link service allow you shorten links

Key generation service pre generate unique keys, depending on algorithm

Algorithm factory register all algorithms

Number service allow you concurently generate increment value in database

Notes:

In base62 implementation every long url refference on unique integer, that converts to base62 (digits and alphabetical symbols). Key grows up to 62^n( 56 800 235 584 unique keys for 6 chars size)
