openstack/cinder

Mar 2014 - Feb 2015

OpenStack Block Storage (Cinder). Mirror of code maintained at opendev.org.

Role in this project:

Back-end Developer

Contributions:10 commits in 11 months

Contributions summary:Steven's contributions focused on enhancing the OpenStack Cinder block storage service, primarily addressing pagination and filtering in the API. They implemented fixes for the "next" link in volume APIs, ensuring it's included in detailed queries and handles limits correctly. The user also moved filtering logic from the API layer to the database layer, improving the handling of filters and limits. Furthermore, they addressed a missing "refresh" keyword in the `get_volume_stats` function across multiple drivers to provide consistency.
