ScyllaDB Whitepapers

Scylla delivers the most scalable, fastest and most reliable NoSQL database as a managed service. This paper provides an overview of Scylla Cloud and explains the underlying technology that makes Scylla not only more performant than other DBaaS options but also much more cost-effective.

Scaling Up versus Scaling Out: Mythbusting Database Deployment Options for Big Data

While scaling out the database is the norm for Big Data systems, there are many hidden costs and complexities associated with “node sprawl” that can be remedied by instead deploying smaller clusters of larger database nodes. This paper explores the merits of small clusters and shares test results that debunk the concerns some organizations have about using large nodes.

Building the Real-Time
Big Data Database: Seven Design Principles behind Scylla

In this paper we explain the key design decisions that went into building a drop-in replacement for Apache Cassandra with scale-up performance of 1,000,000 IOPS per node, scale-out to hundreds of nodes and 99% latency of less than 1 millisecond. Accomplishing this called for rethinking many of the foundational architectural choices behind other NoSQL databases.

Applying Control Theory to Create a Self-Optimizing Database: The Technology Underpinnings of ScyllaDB’s Autonomous NoSQL Database

Scylla was architected and implemented by engineers with deep-level knowledge of operating systems and distributed systems, complemented by an appreciation for the power of control theory. A foundational architectural principle, self-optimizing capabilities manifest themselves in every aspect of the Scylla database.

Scylla vs. Amazon DynamoDB: Evaluating NoSQL Databases for Performance and Cost

In this paper, we compare Scylla with Amazon DynamoDB. We’ll cover the detailed methodology of our testing before demonstrating that Scylla performs significantly better than Amazon DynamoDB under real-world conditions. Our evaluation also demonstrates that Scylla delivers significant cost savings over Amazon DynamoDB.

With the release of Scylla Open Source 3.0, we’ve introduced a rich set of new features for more efficient querying, reduced storage requirements, lower repair times, and better overall database performance. Already the industry’s most performant NoSQL database, Scylla now includes production-ready features that surpass the capabilities of Apache Cassandra.

Over-eager ingestion can result in a buildup of queues of background writes, possibly to the point of depleting available memory.This paper explains how Scylla ensures that ingestion of data proceeds as quickly as possible, but not quicker.

Migration Guide: Apache Cassandra to Scylla

Scylla is a drop-in replacement for Apache Cassandra. Transitioning from Cassandra to Scylla is very straightforward. This guide covers the multi-step process of migrating the data and verifying its consistency.
