For a highly technical product like Scylla, the success or failure of its adoption rests heavily in knowledge transfer to the community. Documentation is fundamental to that. To find out what’s new and what’s hot in Scylla documentation, I went to the source and had this exchange with Laura Novich, Senior Technical Writer for ScyllaDB.
We recently launched Scylla Cloud, allowing you to get the most out of Scylla while not having to burden yourself with cluster management tasks. In this blog post we will cover the initial onboarding process, including creating an account and spinning up a cluster.
Today, we publicly announced Scylla Cloud, our fully-managed database as a service (DBaaS). Scylla Cloud is available immediately on Amazon Web Services (AWS) Elastic Cloud 2 (EC2) instances—including a developer instance that makes prototyping incredibly affordable. It will soon also run on Google Cloud and Microsoft Azure public cloud platforms.
“Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run at least twice as fast as that!” — The Red Queen to Alice, Alice Through the Looking Glass In the world of Big Data, if you are not constantly evolving you are already falling behind. This is at the heart of the Red Queen syndrome, which was first applied to the evolution of natural systems. It applies just as much to the evolution of technology. ‘Now! Now!’ cried the Queen. ‘Faster! Faster!’ […]
Scylla Open Source 3.0 ships with a new format for on-disk representation, SSTable 3.0. In this article, we will discuss some of the benefits that emerge from the adoption of this format and the scenarios in which they apply. We will discuss the differences between the old and new formats, and demonstrate use cases in which the new format has significant advantages, and others where the advantages are much smaller. This is truly a situation of “Your Mileage May Vary.” For example, in one test result below, we were able to show a 53% reduction in table size. Other use […]
In a previous blog post we examined how Scylla’s paging works, explained the problems with it and introduced the new stateful paging in Scylla 2.2 that solves these problems for singular partition queries by making paging stateful. In this second blog post we are going to look into how stateful paging was extended to support range-scans as well in Scylla Open Source 3.0. We were able to increase the throughput of range scans by 30% and how we also significantly reduced the amount of data read from the disk by 39% and the amount of disk operations by 73%. A […]
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 […]
When choosing a database, it’s important that it is highly available and can scale. In this post, we will go over Scylla’s highly-available architecture.
