Performance tuning - A key to successful cassandra migrationRamkumar Nottath
In last few years, technology has seen a major drift in the dominance of traditional / RDMBS databases across different domains. Expeditious adoption of NoSQL databases especially Cassandra in the industry opens up a lot more discussions on what are the major challenges that are faced during implementation of Cassandra and how to mitigate it. Many a times we conclude that migration or POC (proof of concept) is not successful; however the real flaw might be in the data modeling, identifying the right hardware configurations, database parameters, right consistency level and so on. There's no one good model or configuration which fits all use cases and all applications. Performance tuning an application is truly an art and requires perseverance. This paper delve into different performance tuning considerations and anti-patterns that need to be considered during Cassandra migration / implementation to make sure we are able to reap the benefits of Cassandra, what makes it a ‘Visionary’ in 2014 Gartner’s Magic Quadrant for Operational Database Management Systems.

Abstract:
With the ever growing size and complexity of enterprise systems there is a pressing need for more detailed application performance management. Due to the high data rates, traditional database technology cannot sustain the required performance. Alternatives are the more lightweight and, thus, more performant key-value stores. However, these systems tend to sacrifice read performance in order to obtain the desired write throughput by avoiding random disk access in favor of fast sequential accesses.
With the advent of SSDs, built upon the philosophy of no moving parts, the boundary between sequential vs. random access is now becoming blurred. This provides a unique opportunity to extend the storage memory hierarchy using SSDs in key-value stores. In this paper, we extensively evaluate the benefits of using SSDs in commercialized key-value stores. In particular, we
investigate the performance of hybrid SSD-HDD systems and demonstrate the benefits of our SSD caching and our novel dynamic schema model.

A Detailed Look At cassandra.yaml (Edward Capriolo, The Last Pickle) | Cassan...DataStax
Successfully running Apache Cassandra in production often means knowing what configuration settings to change and which ones to leave as default. Over the years the cassandra.yaml file has grown to provide a number of settings that can improve stability and performance. While the file contains plenty of helpful comments, there is more to be said about the settings and when to change them.
In this talk Edward Capriolo, Consultant at The Last Pickle, will break down the parameters in the configuration files. Looking at those that are essential to getting started, those that impact performance, those that improve availability, the exotic ones, and the ones that should not be played with. This talk is ideal for someone someone setting up Cassandra for the first time up to people with deployments in productions and wondering what the more exotic configuration options do.

Lessons Learned on Java Tuning for Our Cassandra Clusters (Carlos Monroy, Kne...DataStax
Customizing JVM settings for the needs of an application can be a tricky business, especially when running externally developed software such as Cassandra. In this talk I will share our experiences and the procedure that we have used to test and validate changes with Java tuning. We'll explore with two recent experiences: changes and monitoring of G1 garbage collection, and moving buffer objects off the heap.
For the talk, I'll discuss our tuning process at Knewton. I will share some of the challenges that we faced while identifying what we expected to learn. I'll discuss how we isolated and minimized variables across tests, the importance of the duration of these tests, and how we try to separate correlation from causation. I will demonstrate how to use and interpret the results of the custom scripts that we were driven to develop to gain visibility into our G1GC processes; these scripts will be open sourced.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
