Simple cache microservice

Задача : разработать МС кеша. С данным МС может работать большое кол-во систем. Время хранения записи не устанавливается, однако спустя некоторое время запись можно пометить как ненужную/удалить.

API

  • POST /
    • params:
      • 'key' - for key
      • 'value' - for value
  • GET /{key}
    • return 404 if not found, or value if it's associated with key

Examples :

curl -v -X POST -H "Content-Type: application/json" -d '{"key": "2", "value": "4"}' "http://localhost:8080"

 Note: Unnecessary use of -X or --request, POST is already inferred.
