Data Storage API

Implement a small HTTP service to store objects organized by repository. Clients of this service should be able to GET, PUT, and DELETE objects.

General Requirements

• The service should de-duplicate data objects by repository.
• The service should listen on port 8282.
• The data can be persisted in memory, on disk, or wherever you like.
• The service must implement the API as described below.

Quickstart

Setup

$ poetry install
$ poetry shell
$ export FLASK_APP=data_storage_api.apps.http:create_app
$ export FLASK_ENV=development  # or production

Run

$ poetry run flask run  -h 0.0.0.0 -p 8282

Testing

$ pytest

API

Upload an Object

The repositories are created when performing a request against to the url containing the name of the repository.

e.g.

ending a request to /data/test-repo/ will create test-repo repo in case it doesn't exist yet.

PUT /data/{repository}

Response

Status: 201 Created
{
  "oid": "2845f5a412dbdfacf95193f296dd0f5b2a16920da5a7ffa4c5832f223b03de96",
  "size": 1234
}

Download an Object

GET /data/{repository}/{objectID}

Response

Status: 200 OK
{object data}

Objects that are not on the server will return a 404 Not Found.

Delete an Object

DELETE /data/{repository}/{objectID}

Response

Status: 200 OK
