Elephant
Elephant is an S3-backed key-value store with querying powered by Elastic Search. Your data is persisted on S3 as simple JSON documents, but you can instantly query it over HTTP.
Suddenly, your data becomes as durable as S3, as portable as JSON, and as queryable as HTTP. Enjoy!
Usage
>>> requests.post('http://elephant-server/pages/', data={'title': 'Test Page', 'draft': True})
<Response [200]>
>>> requests.get('http://elephant-server/pages/', params={'q': 'draft:True'}).json()
{u'records': [{u'epoch': 1364286524987, u'title': u'Test Post', u'uuid': u'ce251e8a-ab6b-4f7e-bdc4-eecf0e71ac16', 'draft': True}}Configuration
Elephant expects the following environment variables to be set:
# AWS Credentials AWS_ACCESS_KEY_ID = xxxxxx AWS_SECRET_ACCESS_KEY = xxxxxx # Elastic Search Server ELASTICSEARCH_URL = xxxxxx # Instance Name CLUSTER_NAME = xxxxxx # Instance Password API_KEY = xxxxxx
If you need an Elastic Search to test against, checkout heroku-elasticsearch.
Management
Reseeding ElasticSearch is super simple:
$ python elephant.py purge Deleting all indexes... $ python elephant.py seed Calculating Indexes... [################################] 378/378 Creating Indexes... Indexing... [#### ] 29/378
