This is part one of a two-part blog series on the relative performance of the recently released Apache Cassandra 4.0. In this post we’ll compare Cassandra 4.0 versus Cassandra 3.11. In part two of this series, we’ll compare both of these Cassandra releases with the performance of Scylla Open Source 4.4.

Apache Cassandra 3.0 was originally released in November of 2015. Its last minor release, Cassandra 3.11, was introduced in June of 2017. Since then users have awaited a major upgrade to this popular wide column NoSQL database. On July 27, 2021, Apache Cassandra 4.0 was finally…

More and more teams are choosing our Scylla Cloud as their database-as-a-service. To make this transition even easier, in this post we’ll go step-by-step into what it takes to get your Scylla Cloud cluster up and running quickly.

First Steps

  1. If you haven’t already, sign up for a new Scylla Cloud account
  2. Recommended: Set up Two-Factor Authentication (2FA) for your Scylla Cloud user account.
  3. Optional: Take advantage of our free trial offering and immediately create your first cluster.
  4. Recommended: After setting up your free trial, check out our Scylla University Scylla Cloud lab session that walks you through all…

Today, we’re announcing the general availability of Scylla Cloud on Google Cloud. Scylla Cloud is our resilient, highly performant, fully managed NoSQL database-as-service (DBaaS). Since its release, Scylla has become the go-to for companies that need a database built from the ground up for modern cloud environments. In 2019 we introduced Scylla Cloud, our fully-managed DBaaS. Initially available on AWS, users discovered Scylla Cloud made it easier for them to operate and scale their NoSQL workloads, since it alleviated them from administrative burdens. …

This past week Cassandra 4.0 was finally released as GA, six years after the previous major release.

Initially developed as an open source alternative to Amazon DynamoDB and Google Cloud Bigtable, Cassandra has had a major impact on our industry. To the surprise of none, it eventually became one of the 10 most popular databases — quite an achievement! We at ScyllaDB were inspired by Cassandra seven years ago when we first decided to reimplement it in C++ in a close-to-hardware design while keeping its symmetric, scale-out architecture.

Cassandra’s impact continues to echo through our industry. Even…

Like countless other organizations, you are probably already running various cloud services on AWS. You’re running all kinds of compute instances, and using a bunch of other AWS services besides databases. If your company is big enough, you have a CFO who is looking at a single AWS bill; they really don’t want a cloud-based service to add another markup on top of the current spend. You’d like to simplify and have all of your AWS spending tallied up in one place. Plus, within your own AWS Account you likely have pre-negotiated discounts.

With Scylla Cloud BYOA…

This post aims to help selecting the most cost effective and operationally simple configuration of DynamoDB tables.

TLDR; Choosing the Right Mode

Making sense of the multitude of scaling options available for DynamoDB can be quite confusing, but running a short checklist with a calculator can go a long way to help.

  1. Follow the flowchart below to decide which mode to use
  2. If you have historical data of your database load (or an estimate of load pattern), create a histogram or a percentile curve of the load (aggregate on hours used) — this is the easiest way to observe how many…

Summer’s here! Which means that we’re getting ready for our Scylla University LIVE Summer School session. We hope to meet you all there. Meanwhile, behind the scenes we’ve been diligently working to deliver new software across our product set — the database itself, drivers (Rust 0.2), our k8s operator, Spark Migrator, and the list goes on.

Project Circe aims to make Scylla, already a kickass database, even better. With that goal in mind, here’s a look at our progress for the month of June.

Scylla Open Source 4.5 Coming Soon!

We’re on the verge of releasing Scylla Open Source 4.5 (following RC2, which…

Recently I had the privilege to host a webinar with some very good friends of ScyllaDB, including Numberly’s CTO Alexys Jacob and Chief Data Officer Othmane El Metioui, as well as Tim Berglund, the Senior Director of Developer Relations at Confluent. They were joined by my colleague Maheedhar “Mahee” Gunturu, our Director of Technical Alliances.

Numberly: Combining the Power of Scylla and Kafka

Mahee turned the session over to Alexys Jacob of Numberly, who described the French AdTech company’s current architecture and its constituent components.

“At Numberly we run both Scylla and Confluent Kafka on premises on bare metal machines. This means that this…

At Scylla Summit 2021, we were joined by two members of the engineering team at Grab, Chao Wang and Arun Sandu, who generously provided their insights into the ways that Grab is using Scylla to solve multiple business challenges at scale.

Chao works on Grab’s Trust team, where he is helping to build out a machine learning-driven fraud detection platform. Arun works on design, automation, and cloud operations for Grab’s NoSQL datastores.

The Grab platform is one of Southeast Asia’s largest, providing an all-in-one app used daily by tens of millions of people to shop, hail rides, make payments, and…

Project Circe is ScyllaDB’s year-long initiative to make Scylla, already the best NoSQL database, even better. We’re sharing our updates for the month of May 2021.

Operational Improvements

Better failure detection

Failure detection is now done directly by nodes pinging each other rather than through the gossip protocol. This is more reliable and the information is available more rapidly. Impact on networking is low, since Scylla implements a fully connected mesh in all clusters smaller than 256 nodes per datacenter, which is much larger than the typical cluster.

SLA per workload

Scylla supports multiple workloads, some with real-time guarantees, some have batch nature where latency…
