In OpenStack, which project stores and retrieves arbitrary unstructured data objects?
The project in OpenStack that stores and retrieves arbitrary unstructured data objects is Swift.
Swift is an open-source, highly available, distributed, and eventually consistent object storage system. It provides a simple and scalable solution for storing and retrieving large amounts of unstructured data, such as images, videos, backups, and archives. Swift is designed to be fault-tolerant and resilient, with built-in replication and self-healing capabilities.
Swift's architecture is based on a cluster of storage nodes that work together to provide a unified object storage service. Each storage node runs a set of services that communicate with each other using a RESTful API over HTTP. The storage nodes store objects as files in a distributed file system, which can be accessed using the Swift API.
Swift is integrated with other OpenStack projects, such as Keystone (identity service) and Horizon (dashboard). It also provides a command-line interface (CLI) and a set of SDKs for developers to interact with the Swift API.
In summary, Swift is the OpenStack project that provides a scalable and fault-tolerant object storage service for arbitrary unstructured data objects.
