ScyllaDB Manager vs SWC-DB

ScyllaDB Manager is a free, open-source, self-hosted tool for automating operations on ScyllaDB clusters. It schedules backups, repairs, and cluster-status checks, and can coordinate tasks across multiple clusters. The system includes a Manager Server daemon with a REST API, the sctool command-line client, and an Agent daemon on every ScyllaDB node. The Server stores its data in a local or external ScyllaDB cluster. A monitoring dashboard is included, while ScyllaDB Monitoring Stack can add metrics and alerts. Documented backup destinations include Amazon S3, compatible S3 storage, Google Cloud Storage, Azure Blob Storage, and local storage. Agents communicate over HTTPS with configurable TLS settings. Installation guidance covers Red Hat Enterprise Linux 8 and 9, Debian 11 and 12, and Ubuntu 22.04 and 24.04. A minimal server needs 2 cores and 1GB RAM; the recommended setup is 2 vCPUs and at least 8GB DRAM.

SWC-DB is a self-hosted Super Wide Column Database that the maker describes as a key-value, wide-column NoSQL and time-series database. It supports SQL, but SQL has no joins, and the system is designed for very large data volumes. Its data model uses cell keys made from lists of fractions with timestamps, with numerous columns rather than tables or namespaces. Data can have automatic or user-defined versions, ordered ascending or descending, with a configurable maximum retained. The maker describes ACID concepts for a single data entry; writes across multiple entries are not atomic as a group. Communications can use SSL, but transaction security also depends on the configured filesystem and clients supporting a secure layer. User-concept access controls are unsupported. A cluster utility can deploy, start and stop distributed clusters. Downloads include tar.xz and Debian packages, with Arch Linux AUR packages also described. SWC-DB is free under GPLv3; commercial-purpose licensing inquiries are invited for uses limited by that license.
