CubeFS is a CNCF graduated cloud-native distributed file system supporting POSIX, HDFS, and S3-compatible object storage protocols. It provides multi-tenancy, multi-AZ deployment, cross-region replication, and erasure coding for both hot and cold data tiers, and is widely used to back cloud-native AI training, big-data analytics, and container storage workloads.
CubeFS publishes 11 APIs on the APIs.io network, including Buckets API, Cluster API, DataPartitions API, and 8 more. Tagged areas include Cloud-Native, CNCF Graduated, Distributed File System, Kubernetes, and Object Storage.
The CubeFS catalog on APIs.io includes 1 JSON-LD context and 3 Spectral governance rulesets.
CubeFS’s developer surface includes authentication, documentation, getting-started guide, changelog, and 17 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Open Source Surface applies to this provider. This product is open source and we
read its repository directly, so Open Source Surface carries
10 points of the composite. It is scored from what the repository actually
publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the
provider rather than inferred from our own catalog pointers.
This facet adds; nothing was taken away to make room for it. An open-source project is not excused from
the commercial facets, because exemption would strip it of the points it does earn.
If we have the wrong repository, or this product is not open source, say so on your
provider repo and we
will drop the facet rather than have you publish against it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 65 points between them,
because both conditional facets apply and carry
35 points together. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 65% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cubefs: open an issue to ask a question, or submit a pull request to add artifacts.

Interfaces this provider implements that became standards by being copied rather than ratified. Each is profiled by the API Commons, and the evidence column says how the claim was established — not that it was made.
Bucket-level operations including creating, listing, and deleting buckets. In CubeFS, each S3 bucket corresponds to a CubeFS volume. Bucket names must be unique within the cluster.
Multipart upload operations for uploading large objects in parts. Supports initiating, uploading parts, listing parts, completing, and aborting multipart uploads.
Object CRUD operations including uploading, downloading, copying, listing, and deleting objects. Supports both standard single-part uploads and multipart uploads for large objects.
User and access control management for CubeFS multi-tenancy. Users own volumes and are assigned access keys and secret keys for S3-compatible object storage operations.
Volume lifecycle management operations including creating, updating, expanding, shrinking, and deleting volumes. Volumes are the top-level storage namespaces in CubeFS.
Discovery needs no key. Ratings and market analysis are Pro.
