FireEye is a NASDAQ-traded cybersecurity firm that offers a broad portfolio ranging from a robust enterprise threat intelligence platform, hardware appliances to managed defenses and security consulting. Its customers span the gamut from global telecommunications giants to healthcare providers, universities to research facilities, financial institutions to school systems, municipalities, states, and government ministries. In such an environment, where being wrong only once can lead to damaging and even dangerous breaches, security analytics must keep up with the velocity and volume of the threats faced at Internet scale. At Scylla Summit 2019, Rahul Gaikwad and Krishna Palati of the FireEye Threat […]
A question we keep getting from customers is: “How can I monitor Scylla with Datadog?” And more generally “How do you integrate Datadog and Prometheus?” Find out how to enable this on your Scylla cluster.
This article presents the extensions done to the Scylla Migrator to also support data movement between an existing DynamoDB installation and Scylla.
About Scylla’s Alternator Project Alternator is an open source project that gives Scylla compatibility with Amazon DynamoDB™. Our goal is that any application written for Amazon DynamoDB could be run, unmodified, against Scylla with Alternator enabled. Originally, Scylla began as a re-implementation of Apache Cassandra, and it has since proven to be a solid database engine with key performance and TCO benefits over Cassandra. However, we always considered Cassandra to be just a starting point. Now a 5-year old project, Scylla is able to scale to hundreds of machines, petabytes of data and many regions and availability zones. Scylla can […]
Anyone who’s tried to build such a solution knows that one of the chief difficulties is encompassing the sheer number and complexity of existing data sources. In order to deliver a true solution, we need to be able to bring this disparate data together. A graph data system, built with JanusGraph and backed by the power of Scylla, is a great fit for solving this problem.
Scylla’s March 2019 webinar on database migration drew broad interest and will likely remain a popular topic for years to come. So, you’ve decided to adopt Scylla (or Cassandra). What’s the best way to get your Big Data uploaded into your new cluster? What strategies, tools and techniques can you use to get your terabytes or petabytes from point A to point B? Those were the questions of the day for Dan Yasny, Field Engineer of ScyllaDB.
Another week, another Spark and Scylla post! This time, we’re back again with the Scylla Spark Migrator; we’ll take a short tour through its innards to see how it is implemented. Read why we implemented the Scylla Spark Migrator in this blog. Overview When developing the Migrator, we had several design goals in mind. First, the Migrator should be highly efficient in terms of resource usage. Resource efficiency in the land of Spark applications usually translates to avoiding data shuffles between nodes. Data shuffles are destructive to Spark’s performance, as they incur more I/O costs. Moreover, shuffles usually get slower […]
CHECK OUT PART ONE OF THIS BLOG We covered the basics of Elasticsearch and how Scylla is a perfect complement for it in part one of this blog. Today we want to give you specific how-tos on connecting Scylla and Elasticsearch, including use cases and sample code. Use Case #1 If combining a persistent, highly available datastore with full text search engine is a market requirement, then implementing a single, integrated solution is an ultimate goal that requires time and resources. To answer this challenge we describe below a way for users to use best-of-breed solutions that support full text […]
Derek Ramsey, Software Engineering Manager at Sensaphone, gave an overview of ValuStor at Scylla Summit 2018. Sensaphone is a maker of remote monitoring solutions for the Industrial Internet of Things (IIoT). Their products are designed to watch over your physical plant and equipment — such as HVAC systems, oil and gas infrastructure, livestock facilities, greenhouses, food, beverage and medical cold storage. Yet there is a lot of software behind the hardware of IIoT. ValuStor is an example of ostensible “hardware guys” teaching the software guys a thing or two. Overview and Origins of ValuStor Derek began his Scylla Summit talk […]
Welcome to a whole new chapter in our Spark and Scylla series! This post will introduce the Scylla Migrator project – a Spark-based application that will easily and efficiently migrate existing Cassandra tables into Scylla. Over the last few years, ScyllaDB has helped many customers migrate from existing Cassandra installations to a Scylla deployment. The migration approach is detailed in this document. Briefly, the process is comprised of several phases: Create an identical schema in Scylla to hold the data; Configure the application to perform dual writes; Snapshot the historical data from Cassandra and load it into Scylla; Configure the […]
