## Goal:

Create an API server which can analyse the content of big xml files

A distributable docker container running the server (Bonus)

## Requirement:

- Create an API with Spring Boot (Java) and Maven.

- A POST request should be possible with a url to an XML file (this file can be > 1GB)

- The response of the post request should hold an overview of the analysation of the XML (see example below, feel free to add more fields).

- The code should be unit and component tested.

- The code should pass the maven build and be runnable via cli with max of 512MB of memory.

At least a single Java 8 feature should be included.

### Request

``curl -i -X POST \

     -H "Content-Type:application/json" \

     -d \

  '{

    "url": "{{url}}"

  }' \

   'http://localhost:8080/analyze/'``

   

#### Response:

``{  

     "analyseDate":"2016-04-25T14:52:30+00:00",

     "details" {

         "firstPost":"2016-01-12T18:45:19.963+00:00",

         "lastPost":"2016-03-04T13:30:22.410+00:00",

         "totalPosts":80,

         "totalAcceptedPosts":7,

         "avgScore":13

     }

  }``

   

## Run application

Latest image will be pulled from Docker Hub. 

Just copy docker-compose.yml and run ``docker-compose up -d``

## Ideas for improvements

- Service has been impemented accordingly to specified contract so solution is synchronous but to prevent requests that take up to several minutes, asynchronous implementation could be used

- Storing information about processed file to prevent calculating same file (based on some assumtions like: file size, given file from particular uri and size has been processed, returned persisted data about file details)
