SWC-DB

Product: SWC-DB describes itself as a high-performance, scalable Super Wide Column Database.
Data model: The documentation identifies SWC-DB as a key-value, wide-column, NoSQL and time-series database.
Scale: The maker says the system is designed for yottabytes of data and a quadrillion base of entries.
SQL: SWC-DB supports SQL, but the maker notes that it has no joins.
Transactions: The maker describes ACID concepts for a single data entry, while multi-entry writes are not atomic as a group.
Keys and columns: Its cell keys are lists of fractions with timestamps, and it has numerous columns without tables or namespaces.
Versions: The maker says data can use automatic or user-defined versions, with ascending or descending order and a configurable maximum to keep.
Security: The documentation says communications can use SSL, while transaction security also depends on the configured filesystem and clients supporting a secure layer.
Access control: The maker's feature checklist marks user-concept access controls as unsupported.
Client languages: The Thrift client documentation lists C++, Java, Python, Ruby and C-Glib libraries, plus generated clients for .NET Standard and Rust.
Filesystem options: Build options list local, broker, Hadoop JVM, Hadoop and Ceph as built-in filesystem choices.
Deployment: The maker documents a cluster utility with commands to deploy, start and stop a distributed SWC-DB cluster.
Downloads: The download page offers tar.xz and Debian packages and describes Arch Linux AUR packages.
Support: The maker directs users to a Google Group for discussions and help, GitHub issues for bugs or feature requests, and lists commercial support contact options.
