Element Fleet has the largest benchmark database in our industry and we needed a robust and linearly scalable platform to turn this data into actionable insights for our customers. The platform needed to support advanced analytics, streaming data sets, and traditional business intelligence use cases.
In this presentation, we will discuss how we built a single, unified platform for both Advanced Analytics and traditional Business Intelligence using Cassandra on DSE. With Cassandra as our foundation, we are able to plug in the appropriate technology to meet varied use cases. The platform we’ve built supports real-time streaming (Spark Streaming/Kafka), batch and streaming analytics (PySpark, Spark Streaming), and traditional BI/data warehousing (C*/FiloDB). In this talk, we are going to explore the entire tech stack and the challenges we faced trying support the above use cases. We will specifically discuss how we ingest and analyze IoT (vehicle telematics data) in real-time and batch, combine data from multiple data sources into to single data model, and support standardized and ah-hoc reporting requirements.
About the Speaker
Jim Peregord Vice President - Analytics, Business Intelligence, Data Management, Element Corp.
Primary and Clustering Keys should be one of the very first things you learn about when modeling Cassandra data. Most people coming from a relational background automatically think, ""Yeah, I know what a Primary Key is"", and gloss right over it. Because of this, there always seems to be a lot of confusion around the topic of Primary Keys in Cassandra. This presentation will demystify that confusion. I will cover what the different types of Keys are, how they can be used, what their purpose is, and how they affect your queries.
For this presentation, I will be using CrossFit gym locations as my subject matter. I will explain the differences between Primary Keys, Compound Keys, Clustering Keys, & Composite Keys. I will also show how the data behind each type differs as stored on disk. Lastly, I will show what queries each type of key will support.

Talk on Apache Kudu, presented by Asim Jalis at SF Data Engineering Meetup on 2/23/2016.
http://www.meetup.com/SF-Data-Engineering/events/228293610/
Big Data applications need to ingest streaming data and analyze it. HBase is great at ingesting streaming data but not good at analytics. HDFS is great at analytics but not at ingesting streaming data. Frequently applications ingest data into HBase and then move it to HDFS for analytics. What if you could use a single system for both use cases?
What if you could use a single system for both use cases? This could dramatically simplify your data pipeline architecture.
This is where Kudu comes in. Kudu is a storage system that lives between HDFS and HBase. It is good at both ingesting streaming data and good at analyzing it using Spark, MapReduce, and SQL.
This document discusses tools for developers working with Cassandra and DSE Graph databases. It outlines tools for analysis and design, data loading, and development. It introduces the DataStax DevCenter IDE for working with schemas and queries, and DataStax Studio for exploring, analyzing, and visualizing DSE Graph data. Finally, it discusses DataStax drivers, connectors for Spark and Kafka, and tools for testing like CCM and cassandra-unit.
Infosys Ltd: Performance Tuning - A Key to Successful Cassandra MigrationDataStax Academy
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.
This document discusses real time analytics using Spark and Spark Streaming. It provides an introduction to Spark and highlights limitations of Hadoop for real-time analytics. It then describes Spark's advantages like in-memory processing and rich APIs. The document discusses Spark Streaming and the Spark Cassandra Connector. It also introduces DataStax Enterprise which integrates Spark, Cassandra and Solr to allow real-time analytics without separate clusters. Examples of streaming use cases and demos are provided.
1) Hadoop is well-suited for organizations that have large amounts of non-relational or unstructured data from sources like logs, sensor data, or social media. It allows for the distributed storage and parallel processing of such large datasets across clusters of commodity hardware.
2) Hadoop uses the Hadoop Distributed File System (HDFS) to reliably store large files across nodes in a cluster and allows for the parallel processing of data using the MapReduce programming model. This architecture provides benefits like scalability, flexibility, reliability, and low costs compared to traditional database solutions.
3) To get started with Hadoop, organizations should run some initial proof-of-concept projects using freely available cloud resources

January 2015 HUG: Using HBase Co-Processors to Build a Distributed, Transacti...Yahoo Developer Network
Monte Zweben Co-Founder and CEO of Splice Machine, will discuss how to use HBase co-processors to build an ANSI-99 SQL database with 1) parallelization of SQL execution plans, 2) ACID transactions with snapshot isolation and 3) consistent secondary indexing.
Transactions are critical in traditional RDBMSs because they ensure reliable updates across multiple rows and tables. Most operational applications require transactions, but even analytics systems use transactions to reliably update secondary indexes after a record insert or update.
In the Hadoop ecosystem, HBase is a key-value store with real-time updates, but it does not have multi-row, multi-table transactions, secondary indexes or a robust query language like SQL. Combining SQL with a full transactional model over HBase opens a whole new set of OLTP and OLAP use cases for Hadoop that was traditionally reserved for RDBMSs like MySQL or Oracle. However, a transactional HBase system has the advantage of scaling out with commodity servers, leading to a 5x-10x cost savings over traditional databases like MySQL or Oracle.
HBase co-processors, introduced in release 0.92, provide a flexible and high-performance framework to extend HBase. In this talk, we show how we used HBase co-processors to support a full ANSI SQL RDBMS without modifying the core HBase source. We will discuss how endpoint transactions are used to serialize SQL execution plans over to regions so that computation is local to where the data is stored. Additionally, we will show how observer co-processors simultaneously support both transactions and secondary indexing.
The talk will also discuss how Splice Machine extended the work of Google Percolator, Yahoo Labs’ OMID, and the University of Waterloo on distributed snapshot isolation for transactions. Lastly, performance benchmarks will be provided, including full TPC-C and TPC-H results that show how Hadoop/HBase can be a replacement of traditional RDBMS solutions.

February 2016 HUG: Apache Kudu (incubating): New Apache Hadoop Storage for Fa...Yahoo Developer Network
Over the past several years, the Hadoop ecosystem has made great strides in its real-time access capabilities, narrowing the gap compared to traditional database technologies. With systems such as Impala and Apache Spark, analysts can now run complex queries or jobs over large datasets within a matter of seconds. With systems such as Apache HBase and Apache Phoenix, applications can achieve millisecond-scale random access to arbitrarily-sized datasets. Despite these advances, some important gaps remain that prevent many applications from transitioning to Hadoop-based architectures. Users are often caught between a rock and a hard place: columnar formats such as Apache Parquet offer extremely fast scan rates for analytics, but little to no ability for real-time modification or row-by-row indexed access. Online systems such as HBase offer very fast random access, but scan rates that are too slow for large scale data warehousing workloads. This talk will investigate the trade-offs between real-time transactional access and fast analytic performance from the perspective of storage engine internals. It will also describe Kudu, the new addition to the open source Hadoop ecosystem with out-of-the-box integration with Apache Spark, that fills the gap described above to provide a new option to achieve fast scans and fast random access from a single API.

Elassandra: Elasticsearch as a Cassandra Secondary Index (Rémi Trouville, Vin...DataStax
Many companies use both elasticsearch and cassandra, typically in the form of logs or time series, but managing many softwares at a large scale can be quite challenging. Elassandra tightly integrates elasticsearch within cassandra as a secondary index, allowing near-realtime search with all existing elasticsearch APIs, plugins and tools like Kibana. We will present the core concepts of elassandra and explain how it draws benefit from internal cassandra features to make elasticsearch masterless, scalable with automatic resharding, more reliable and more efficient than deploying both softwares. We will also explore the bidirectional mapping : the way elasticsearch automatically creates the corresponding cassandra schema and the way elasticsearch indexes an existing cassandra table. Furthermore, we will share some use cases and benchmark results demonstrating practical use of elassandra to scale-out, re-index with zero-downtime, search and visualize data with various tools.

Implementación de un sistema 3D de información de servicios en el subsuelo en...Carles Colás
La recogida e interpretación de la información de conjuntos de activos existentes como las tuberías o cables enterrados puede ser complejo y exigente en cuanto a recursos financieros y humanos. Se puede estar hablando de redes de varios miles de kilómetros de tuberías de diferentes tipos, materiales, edad y estado. Los servicios públicos de todo, frente a estos retos, han desarrollado recientemente un enfoque llamado Asset Management Planning (AMP) o Planificación de Gestión de Activos (PGA). AMP es un enfoque estructurado y disciplinado de la gestión de los activos físicos, y está diseñado fundamentalmente para dar respuesta a las siguientes cuestiones como ¿Cuáles son los activos y donde están situados?
Así, la Gestión de Activos provee una marco para gestionar tanto la planificación a corto como a largo plazo.
Un sistema de gestión de activos de obras públicas puesto en práctica al detalle permitirá a los que toman decisiones determinar cómo cada acción (ej. operar y mantener servicios existentes, así como construir nuevos) puede influir probablemente tanto en los presupuestos actuales como en el bienestar regional a largo plazo.
Superar estos problemas puede suponer una gran dificultad para los servicios públicos de tamaño pequeño y medio, y pueden perjudicar el progreso de sus programas de rehabilitación.

The document discusses lessons learned from integrating MongoDB into eCommerce websites. Some key points:
- The EAV data model used by Magento is slow and performs poorly at scale, motivating a transition to MongoDB.
- Early approaches stored all product data in MongoDB but this broke features relying on SQL. A hybrid model using MongoDB for most attributes and MySQL for key fields worked better.
- The learning curve is high but storing data to match queries, managing transactions carefully, and using search engines are important. Near real-time processing can improve performance significantly.
- Backup and replication require special attention in distributed architectures. The open source MongoGento module developed by Smile improves Magento performance
This document summarizes a system using Cassandra, Spark, and ELK (Elasticsearch, Logstash, Kibana) for processing streaming data. It describes how the Spark Cassandra Connector is used to represent Cassandra tables as Spark RDDs and write RDDs back to Cassandra. It also explains how data is extracted from Cassandra into RDDs based on token ranges, transformed using Spark, and indexed into Elasticsearch for visualization and analysis in Kibana. Recommendations are provided for improving performance of the Cassandra to Spark data extraction.
The document discusses cloud operating systems. A cloud OS runs applications and stores data on remote servers that can be accessed from any internet-connected device. This is different than traditional desktop computing which stores programs and files locally. A cloud OS has several advantages like lower costs, automatic updates, universal access, and unlimited storage. However, it requires an internet connection and performance may be reduced without fast speeds. The document provides examples of cloud OSs, describes their architecture which involves clients connecting to a remote server over the network, and covers applications, demonstrations, storage features, advantages and disadvantages of cloud OSs.

ADV Slides: Platforming Your Data for Success – Databases, Hadoop, Managed Ha...DATAVERSITY
Thirty years is a long time for a technology foundation to be as active as relational databases. Are their replacements here? In this webinar, we say no.
Databases have not sat around while Hadoop emerged. The Hadoop era generated a ton of interest and confusion, but is it still relevant as organizations are deploying cloud storage like a kid in a candy store? We’ll discuss what platforms to use for what data. This is a critical decision that can dictate two to five times additional work effort if it’s a bad fit.
Drop the herd mentality. In reality, there is no “one size fits all” right now. We need to make our platform decisions amidst this backdrop.
This webinar will distinguish these analytic deployment options and help you platform 2020 and beyond for success.
Today, data lakes are widely used and have become extremely affordable as data volumes have grown. However, they are only meant for storage and by themselves provide no direct value. With up to 80% of data stored in the data lake today, how do you unlock the value of the data lake? The value lies in the compute engine that runs on top of a data lake.
Join us for this webinar where Ahana co-founder and Chief Product Officer Dipti Borkar will discuss how to unlock the value of your data lake with the emerging Open Data Lake analytics architecture.
Dipti will cover:
-Open Data Lake analytics - what it is and what use cases it supports
-Why companies are moving to an open data lake analytics approach
-Why the open source data lake query engine Presto is critical to this approach

Old Tools, New Tricks: Unleashing the Power of Time-Tested Testing ToolsBenjamin Bischoff
In the rapidly evolving landscape of software development and testing, it is tempting to chase the latest tools and technologies. However, some of the most effective solutions have been in existence for decades. In this talk, we’ll delve into the enduring value of these timeless testing tools.
We’ll explore how established tools like Selenium, GNU Make, Maven, and Bash remain vital in today’s software development and testing toolkit even though they have been around for a long time (some were even invented before I was born). I’ll share examples of how these tools have addressed our testing and automation challenges, showcasing their adaptability, versatility, and reliability in various scenarios. I aim to demonstrate that sometimes, the “old” ways can indeed be the best ways.
The code is written and the tests pass. I just have to commit this last round of changes to my branch. Wait, why does that say committed to main? Did I commit all those changes to main? Arghh! I can’t redo all of this!
Committing changes to the wrong branch, forgetting files, misspelling the commit message, and needing to undo commits are some of the “advanced” features of Git that we normal people run into way too often and need help with. The fixes are often easy – once you know what they are. But in the heat of the moment, with the deadline (or Friday afternoon) approaching, it isn’t always easy to figure out what magic spell to cast to get Git to do what you need.
We’ll spend some time looking at typical Git situations people get themselves into, and then we’ll demonstrate how to get out of them. This isn’t about Git internals or a Git master’s class – this real-world Git when things aren’t going right. And there will be plenty of time for questions, so bring your “best” Git nightmare scenarios so we can figure out how to recover.

Test Polarity: Detecting Positive and Negative Tests (FSE 2024)Andre Hora
Positive tests (aka, happy path tests) cover the expected behavior of the program, while negative tests (aka, unhappy path tests) check the unexpected behavior. Ideally, test suites should have both positive and negative tests to better protect against regressions. In practice, unfortunately, we cannot easily identify whether a test is positive or negative. A better understanding of whether a test suite is more positive or negative is fundamental to assessing the overall test suite capability in testing expected and unexpected behaviors. In this paper, we propose test polarity, an automated approach to detect positive and negative tests. Our approach runs/monitors the test suite and collects runtime data about the application execution to classify the test methods as positive or negative. In a first evaluation, test polarity correctly classified 117 tests as as positive or negative. Finally, we provide a preliminary empirical study to analyze the test polarity of 2,054 test methods from 12 real-world test suites of the Python Standard Library. We find that most of the analyzed test methods are negative (88%) and a minority is positive (12%). However, there is a large variation per project: while some libraries have an equivalent number of positive and negative tests, others have mostly negative ones.

PathSpotter: Exploring Tested Paths to Discover Missing Tests (FSE 2024)Andre Hora
When creating test cases, ideally, developers should test both the expected and unexpected behaviors of the program to catch more bugs and avoid regressions. However, the literature has provided evidence that developers are more likely to test expected behaviors than unexpected ones. In this paper, we propose PathSpotter, a tool to automatically identify tested paths and support the detection of missing tests. Based on PathSpotter, we provide an approach to guide us in detecting missing tests. To evaluate it, we submitted pull requests with test improvements to open-source projects. As a result, 6 out of 8 pull requests were accepted and merged in relevant systems, including CPython, Pylint, and Jupyter Client. These pull requests created/updated 32 tests and added 80 novel assertions covering untested cases. This indicates that our test improvement solution is well received by open-source projects.
Waze vs. Google Maps vs. Apple Maps, Who Else.pdfBen Ramedani
Let’s face it, getting lost isn’t really part of the adventure anymore (unless you’re into that sort of thing!). Nowadays, a good navigation app is like your trusty compass, guiding you through busy city streets and winding country roads. But with so many options out there—from big names like Waze, Google Maps, and Apple Maps to some lesser-known contenders—choosing the right one can feel a bit overwhelming.
Think about it: you're about to head out on a road trip, and the last thing you want is to end up in the middle of nowhere because you took a wrong turn. Or maybe you're just trying to navigate your daily commute without hitting every single red light. That's where a solid navigation app comes in handy.
Google Maps is like the old reliable friend who knows every shortcut and scenic route. It's packed with features, from real-time traffic updates to detailed directions, making it a top choice for many. But then there's Waze, the social butterfly of navigation apps. It's all about community, with drivers sharing real-time updates on traffic, accidents, and even speed traps. It’s perfect if you want to feel like you’re part of a huge driving club, all working together to get everyone to their destination faster.
And let’s not forget Apple Maps, which has come a long way since its rocky start. If you're deep into the Apple ecosystem, it's a seamless choice, integrating smoothly with all your devices and offering some pretty neat features like Flyover for 3D city views.
But wait, there are also some underdog apps worth considering! Have you heard of MapQuest? It's still around and offers some great features, especially for planning long trips with multiple stops. Then there's HERE WeGo, which is fantastic for offline navigation—a real lifesaver if you're heading somewhere with spotty cell service.
So, whether you're planning a cross-country adventure or just trying to find the quickest route to work, we’ll help you sift through these options. We’ll dive into what makes each app unique, their pros and cons, and ultimately, guide you to the perfect navigation app for your needs. Buckle up and get ready for a smooth ride!
