django-zombodb (via) The hardest part of working with an external search engine like Elasticsearch is always keeping that index synchronized with your relational database. ZomboDB is a PostgreSQL extension which lets you create a new type of index backed by an external Elasticsearch cluster. Updated rows will be pushed to the index automatically, and custom SQL syntax can then be used to execute searches. django-zombodb is a brand new library by Flávio Juvenal which integrates ZomboDB directly into the Django ORM, letting you add Elasticsearch-backed functionality with just a few lines of extra configuration. It even includes custom Django migrations for enabling the extension in PostgreSQL!
