Distributed wide-column NoSQL database for high scalability
Document-oriented NoSQL database with flexible schema
From StackPrism’s curated notes. Pricing isn’t covered here: it changes often, so check each vendor’s pricing page.
Both are NoSQL databases that scale out across many nodes, but they model data differently. Cassandra is a wide-column store designed around high write volumes and multi-datacenter replication; MongoDB stores JSON-like documents and supports flexible ad-hoc queries.
Release lines and end-of-life dates come from endoflife.date, release counts from deps.dev’s publish dates, and advisories from OSV.dev, counted once per flaw even when it’s listed under several ids, and checked against CISA’s list of vulnerabilities known to be exploited. Status and incident history come from each vendor’s public status feed; licences from each project’s licence file or the vendor’s licensing page, linked in the table.
The data refreshes every few hours and the time it was checked is shown above. There’s no pricing and no overall winner: which one fits depends on your constraints. To see how the versions you actually run hold up, check your repo.
