About ScyllaDB
ScyllaDB is a NoSQL database built for low latency and high throughput. It is often chosen as a replacement for Cassandra or DynamoDB when the workload has outgrown them.
What it does
ScyllaDB stores large amounts of data across many nodes and aims for predictable single-digit millisecond response times. Teams use it for feature stores that handle millions of operations per second, for tracking user activity across many live events, and for vector search over large sets of embeddings. It is offered as an enterprise product and as ScyllaDB Cloud, a hosted database service.
Key features
- Predictable latency at large scale
- Migration path for Cassandra and DynamoDB users
- Feature stores and real-time event processing
- Vector search over very large embedding sets
- Hosted option through ScyllaDB Cloud
Who it's for
Platform teams that run high-volume services, data engineers who build feature stores, and companies that want a faster drop-in alternative to an older NoSQL system. Teams that need consistent response times under heavy load tend to evaluate it first.
Pricing and good to know
The site lists an enterprise product, a cloud service and a free technical consultation for teams that are evaluating it. Moving an existing workload is a project of its own, so it helps to measure your current latency and data size before you plan the switch.
Highlights
- Serve reads and writes with low, steady latency
