RocksDB

RocksDB is an embeddable persistent key-value store for fast storage, developed at Facebook (Meta) based on LevelDB. It uses a Log-Structured Merge (LSM) tree design optimized for fast, low-latency storage on flash and RAM. RocksDB provides a C++ library with language bindings for Java, Python, Ruby, Rust, and other languages, and is widely used as the storage engine inside databases, data streaming systems, and distributed key-value stores.

RocksDB is listed with 2 APIs on the APIs.io network. Tagged areas include RocksDB, Key-Value Store, Embedded Database, Storage Engine, and Open Source.

The RocksDB catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

RocksDB’s developer surface includes documentation, getting-started guide, code examples, engineering blog, and 12 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.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document Ask about this →
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship Ask about this →
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author Ask about this →
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey) Ask about this →
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented) Ask about this →

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 the provider profile at artifacts.apis.io/rocksdb/apis.yml: open an issue on github.com/api-evangelist/rocksdb to ask a question or point us at an artifact you publish.
