See you at AWS re:Invent 2018!

Are you planning to attend AWS re:Invent 2018? We’d love to see you! Stop by booth #1910 in the Expo Hall at the Venetian to talk with our solution engineers, learn about Scylla, play our fun iPad game and pick up some cool Sea Monster swag. Our solutions engineers will be on hand for live demos. See for yourself how Scylla uses as little as three i3.metal instances to do millions of transactions per second at single-digit millisecond p99 latencies. We will also demo Scylla Manager, a smart way to control and manage a Scylla cluster and maintain a high […]

Hello again! Following up on our previous post on saving data to Scylla, this time, we’ll discuss using Spark Structured Streaming with Scylla and see how streaming workloads can be written in to ScyllaDB. Our code samples repository for this post contains an example project along with a docker-compose.yaml file with the necessary infrastructure for running the it. We’re going to use the infrastructure to run the code samples throughout the post and run the project itself, so start it up as follows: After that is done, launch the Spark shell as in the previous posts: With that done, let’s […]

Dor Laor addresses Scylla Summit 2018

Scylla Summit 2018 was quite an event! Your intrepid reporter tried to keep up with the goings-on, live-tweeting the event from opening to close.

More Efficient Range Scan Paging with Scylla 3.0

More Efficient Range Scan Paging with Scylla 3.0

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. 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 range scan, or a full […]

The Perfect Hybrid Cloud for IBMHAT

IBM Red Hat Acquisition

The acquisition of Red Hat by IBM caught many, including myself, by surprise. It’s not that such an option was never on the table. During the time I was at Red Hat (2008-2012) such ideas were tossed about. Funny to say, but in 2012 Red Hat seemed too expensive a play. Revenues rose sharply since, and so has the price. Before we dive into whether this move will save IBM, let’s first tip our caps for Red Hat, one of the most important technology companies. Red Hat is an innovator of the open source business model. The leader of the […]

The Dark Side of MongoDB’s New License

SSPL vs. APGL Side-by-Side

It’s never been simple to be an Open Source vendor. With the rise of the cloud and the emergence of software as a service, the open source monetization model continues to encounter risks and challenges. A recent example can be found in MongoDB, the most prevalent NoSQL OSS vendor, which just changed its license from AGPL license to a new, more-restrictive license called SSPL. This article will cover why MongoDB made this change, and the problems and risks of the new model. We’ll show how SSPL broadens the definition of copyleft to an almost impossible extent and argue that MongoDB would […]
