Notable Riak CS Features
|Amazon S3-API Compatibility||
Riak CS has a built-in S3 interface with S3 Access Control List ACL support, which means that you can both use existing S3 tools and frameworks to manage your data and also import and extract data from Amazon directly. The HTTP REST API supports service, bucket, and object-level operations to easily store and retrieve data.
With the Riak CS Reporting API, you can access per-tenant usage data and statistics over network I/O. This reporting functionality supports use cases including accounting, subscription, chargebacks, plugins with billing systems, efficient multi-department utilization, and much more.
|Supports Large Objects of Arbitrary Content Type, Plus Metadata||
Riak CS enables you to store any conceivable data type, such as images, text, video, documents, database backups, or software binaries. Riak CS can store objects into the terabyte size range using multipart file uploads. Riak CS also supports standard Amazon metadata headers.
