Objective :
Create a fully functional scenario of an API architecture using Redis as a cache mechanism. End user will have a benefit of fast response from in-memory database like Redis.
Internal (in house process) :
1. Read from 3rd party Provider (BART API, in this case)
2. Parse, save to database and Redis cache
Public API (exposed to end user) :
1. User API request
2. Read from Redis cache engine
3. If it can't find it in Redis, read from database (reply back) and save a copy into Redis for the next API requests.
Disclaimer :
1. 3rd party Data Provider, referring data provided by https://www.bart.gov/schedules/developers/api
2. The above scenario is developed as a process of learning Elixir
