Bio:
Julien est un développeur OpenStack depuis 4 ans, et des principaux développeurs de Ceilometer
depuis son incubation au sein d'OpenStack. Il travaille comme Principal Software Engineer chez Red Hat.

Pitch:
L'année dernière, un nouveau projet à fait son apparition au sein de Ceilometer: Gnocchi.
Il répond à la problématique de stockage des métriques à grande échelle, problème rencontré
par Ceilometer depuis sa création. Pour se faire, il fournit une API REST d'indexation de
resources et de stockage de séries temporelles.
Durant cette présentation, je vous présenterais les raisons de créations de ce projet,

• Allow PATCH on resources (for example changing "host" or "flavor_id" after a resize)
• Allow to retrieve the list of resources for a user: /v1/resources/?user_id=<foo> -> return all instances too /v1/instances/?user_id=<foo>
• Allow to retrieve the list of resources for a user with details: /v1/resources/?user_id=<foo>&detail=true -> return all instances too with full details (more costs as we need to look in other tables)
• Allow to retrieve the list of resources with timestamp /v1/resources/?started_after=<timestamp>&ended_before=<timestamp>
