This is an application for generating random numbers from geolocation coordinates.
Application consists from 2 main parts:
- worker: reads values from firehose API, filters duplications out and pushes that data to the database. Currently a single instance of SQLLite is used, but one can scale it into multiple db instances and push the data depending on the actual location of the final user
- application instance: it includes a pool (cache) which fetches geo coordinates from the database, computes cache from them and saves in memory. By default puul size is 1000, but it's configurable; Application instance fetches the data from the pull on demand; it's connected to UI and API endpoints to request random numbers based on the following parameters: min,nax - interval in that random numbers will be computed, and N - amount of generated random numbers
Users can request random numbers with UI in the browser or using API endpoints.
Start of the application:
- get firehose token; store it in API_KEY_LAB.txt
- run worker.py; it creates sqllite instance, pulls values from firehose, filters out the duplicates and stores geo location in db
- run app.py; it queries 500 locations, hashes them and stores in the pool; then web interface is created and on demand it pulls the data from the pool and generates a random numbers
UI access: /tbd-7/random
API endpoint: /tbd-7/random/api?min=-5&max=7&N=5
