Overview
ScyllaDB is a distributed NoSQL database that speaks CQL (the Apache Cassandra API) by default and offers an optional DynamoDB-compatible API called Alternator. It uses a shared-nothing, per-core design built on the Seastar framework. The repo is the database server itself, not an AI starter, so it fits this list only as backend infrastructure.
Who it is for: Teams running Cassandra or DynamoDB-style workloads on a self-hosted database
Strengths
- CQL compatibility with Apache Cassandra drivers and tooling
- Optional DynamoDB API (Alternator), enabled through configuration
- Shared-nothing, per-core architecture built on Seastar
- Free hands-on courses available through Scylla University
Weaknesses
- Not an AI project; README mentions no model, vector or LLM features
- Building needs a very recent C++23 toolchain; frozen Docker toolchain recommended
- README gives build-from-source steps only, no packaged install or Docker run
- License is reported as NOASSERTION; check the repo license files
What it needs
- no GPU
- Needs Docker or Podman (frozen build toolchain), C++23 compiler, ninja
