The ScyllaDB team announces the release of Scylla Open Source 4.0.1, a bugfix release of the Scylla 4.0 stable branch. Scylla Open Source 4.0.1, like all past and future 4.x.y releases, is backward compatible and supports rolling upgrades.
At our last Scylla Summit David Blythe took the trip from North Carolina to San Francisco to explain how they were able to migrate away from DataStax to Scylla for their SAS 360 Match platform. He called this transition “changing all four tires while driving an adtech engine at full speed.”
Wireshark is a well known utility that offers snooping on all kinds of network protocols. You can use it to dissect Scylla’s internal protocol, including reading and writing rows, exchanging schema information, gossiping and repairs.
“Our experience with Scylla Cloud has been great. We’ve been meeting and actually exceeding our expectations on our request latency.”
The ScyllaDB team announces the release of Scylla Enterprise 2019.1.8, a production-ready Scylla Enterprise patch release. As always, Scylla Enterprise customers are encouraged to upgrade to Scylla Enterprise 2019.1.8 in coordination with the Scylla support team.
Zeotap’s Vice President of Engineering, Sathish K S, and Principal Data Engineer Saurabh Verma share how they built the “world’s largest native JanusGraph database backed by Scylla” to meet the needs of tracking and correlating 20 billion IDs for users and their devices.
After implementing both APIs — CQL and DynamoDB — we, the Scylla developers, are in a unique position to be able to provide an unbiased technical comparison between the two APIs. The goal of this post is to explain some of the more interesting differences between the two APIs, and how these differences affect users and implementers of these APIs.
With the release of Scylla Open Source 4.0, we’ve introduced a set of production-ready new features, including a DynamoDB-compatible API that lets you to take your locked-in DynamoDB workloads and run them anywhere, a more efficient implementation of Lightweight Transactions (LWT), plus improved and new experimental features such as Change Data capture (CDC), which uses standard CQL tables.
The Scylla team is pleased to announce the release of Scylla Monitoring Stack 3.3. Scylla Monitoring Stack is an open-source stack for monitoring Scylla Enterprise and Scylla Open Source, based on Prometheus and Grafana.
It’s a sure revolution, one that most people haven’t noticed yet. That’s because of two new, exciting interfaces: eBPF (or BPF for short) and io_uring, the latter added to Linux in 2019 and still in very active development. Those interfaces may look evolutionary, but they are revolutionary in the sense that they will — we bet — completely change the way applications work with and think about the Linux Kernel.
