"The simpler the food, the harder it is to prepare well" - Joël Robuchon.

Chef Chef is a data scheduling and normalization service built on Mix Elixir. Just like a chef in a restaurant collects raw ingredients and converts them into recipes, Chef fetches data from multiple match providers, normalized it and persists it into the Postgre database.

Design

• Aggregation of Services Pattern
• Builder pattern

Usage

• mix run --no-halt (to run main application)
• mix test (validate test suit it will start mock cowboy server)
• mock cowboy server endpoint configuration can be configured from config file config/test.exs
• default postgres instance is used for the project can be configured from config file config/config.exs

config :chef,
       Chef.Repo,
       database: "chef_repo",
       username: "postgres",
       password: "postgres",
       hostname: "localhost"

• data fetch interval can be modified using config file config/config.exs as

config :chef,
  # unit milliseconds
  data_fetch_interval: 30000

• mix ecto.create (to create the chef_repo database)
• mix ecto.migrate (to create match_data table to store the normalized data)
