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)
