Apache Cassandra vs ScyllaDB Manager

Apache Cassandra is a free, open-source NoSQL distributed database for mission-critical data and large active datasets. Its masterless architecture gives each node the same functionality. The project says read and write throughput can grow linearly as machines are added, without downtime or application interruption. Cassandra can run on premises, with one cloud provider, across multiple providers, or in a combination of those environments. It supports replication across data centers and configurable consistency levels for queries, along with CQL, transactions, and horizontal scaling. The project lists audit logging for DML, DDL, and DCL activity, and fqltool for recording and replaying production workloads. Drivers are available for Java, Go, Python, and Node.js; downloads include tarballs and packages, and installation guidance covers Debian and RPM. The ecosystem includes tools and connectors for Apache Kafka, Apache Flink, Apache Spark, and Kubernetes. The project identifies version 5.0 as the latest GA release and says it is maintained until the 8.0 release. Cassandra is self-managed, and listed third-party ecosystem projects are not supported by its community.

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.
