Introducing Scylla University

Scylla University

So you’re thinking of running your applications with Scylla? You’ve probably heard it’s a lightning fast, self-optimizing, highly available Apache Cassandra drop-in replacement. Yet you may still have questions like: How do I upgrade from my current system? How many nodes do I need? How do I ensure that my data is consistent across the database? How should applications be written to maximize database performance? How do I scale up or scale out? To make it easier to find answers to these questions and many more, we have launched Scylla University. Anyone in your organization can now take advantage of […]

Scylla Summit Preview: Kiwi.com Migration to Scylla: The Why, the How, the Fails and the Status

In the run-up to Scylla Summit 2018, we’ll be featuring our speakers and providing sneak peeks at their presentations. This interview in our ongoing series is with Martin Strycek of Kiwi.com. His presentation at Scylla Summit is entitled Kiwi.com Migration to Scylla: The Why, the How, the Fails and the Status. Martin, before we get into the details of your talk, we’d like to get to know you a little better. Outside of technology, what do you enjoy doing? What are your interests and hobbies? Thank you for the great opportunity to speak at Scylla Summit. I really like outdoor […]

Large Partitions Support in Scylla 2.3 and Beyond

Large partitions, although supported by Scylla, are also well known for causing performance issues. Fortunately, release 2.3 comes with a helping hand for discovering and investigating large partitions present in a cluster — system.large_partitions table. Large partitions CQL, as a data modeling language, aims towards very good readability and hiding unneeded implementation details from users. As a result, sometimes it’s not clear why a very simple data model suffers from unexpected performance problems. One of the potential suspects might be large partitions. Our blog entry on large partitions contains a detailed explanation on why coping with large partitions is important. […]

In June, Miguel Martinez Pedreira, Software engineer at CERN on the ALICE project, and Glauber Costa, VP of Field Engineering at ScyllaDB, teamed up to do a computing seminar to discuss real-time processing of big data with ScyllaDB, examining how Scylla helped the ALICE experiment with their AliEn Global File Catalogue use case. CERN uses the world’s largest and most complex scientific instruments to study the basic constituents of matter – the fundamental particles. The instruments used at CERN are purpose-built particle accelerators and detectors. Accelerators boost beams of particles to high energies before the beams collide with each other or with […]
