Django Vertica Backend

A proof-of-concept for connecting Django ORM to HP Vertica database.

Current status

• Django ORM SELECT works for some examples
• Django schema dumping works
• Can't run tests on Vertica DB as Vertica doesn't support database creation

Installation

1. install vertica_python and django_vertica_backend
2. edit settings.py

   DATABASES = {
     'default': {
       'ENGINE': 'vertica',
       'NAME': 'dash',
       'HOST': 'localhost',
       'PORT': 5433,
       'USER': 'dbadmin',
       'PASSWORD': 'password'
     }
   }

Example

from django.db.models import Sum
from test_app.models import PlatformReport

qs = PlatformReport.objects.filter(date__gte='2014-09-15')
qs = qs.values('platform_id')
qs = qs.annotate(video_views = Sum('video_views'))
print qs[100:500]
