Standing by category

Every category where a model named Apache Cassandra for a mid-market B2B company. Share is first choices across the direct, paraphrase, budget and scale prompts; rank is within every product named in that category.

Movement

This is the first edition on this tier, so no move can be computed for Apache Cassandra yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

How each model treated Apache Cassandra across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Massive write-heavy, linearly scalable big data → Cassandra” DeepSeek V4 Flash · NoSQL · comparative prompt · first choice
“If you need high scalability and can handle more operational complexity, Apache Cassandra or ScyllaDB are excellent choices.” Mistral Small · NoSQL · budget prompt · alternative
“If you have technical capacity to self-host and want to control long-term costs, go with Apache Cassandra or CouchDB.” Kimi K2 · NoSQL · budget prompt · alternative
“Cassandra (DataStax Astra) | Best for write-heavy distributed workloads, but higher operational complexity.” Kimi K2 · NoSQL · scale prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“it's *extremely* easy to misuse... If you don't have a genuine write-heavy, massive-scale, multi-datacenter requirement, Cassandra is overkill.” DeepSeek V4 Flash · NoSQL · negative prompt · soft negative
“While highly scalable, it defaults to eventual consistency, which can cause issues for applications requiring strong consistency” Mistral Small · NoSQL · negative prompt · soft negative
“For a mid-market B2B company, they are usually "overkill" and require too much specialized engineering maintenance.” Gemini 3.5 Flash · NoSQL · direct prompt · soft negative
“more operational complexity and limited query flexibility. Probably overkill for most mid-market workloads.” DeepSeek V4 Flash · NoSQL · direct prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Apache Cassandra. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 84 of the 115 answers that named Apache Cassandra and are not a share of its labels.

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Apache Cassandra's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Apache Cassandra, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at apache.org is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
