  • Cassandra Meetup: Relaunch at Monzo 🚀

    Hello everyone! The Cassandra meetup is back after a long break with a big relaunch this March at Monzo's office in Central London! For this month's edition we're having 3 talks starting at 7:15pm (Pizza will be before the event starts) and we'll live stream it here: https://www.youtube.com/watch?v=jf4wDDblnNQ // Speaker 1: Hayato Shimizu, Co-Founder at digitalis.io // Speaker 2: Matt Heath, Software Engineer at Monzo // Speaker 2: Cedrick Luven, Developer Advocate at DataStax // Speaker 1 <> 7:15pm: Hayato will discuss "Operational management of Apache Cassandra in Enterprises". Hayato has been using Cassandra since 2010, looking after a large number of Cassandra clusters in both cloud and on-premises environments. He worked as a solutions architect at DataStax, and he is now at a startup providing managed services for Cassandra and DataStax. // Speaker 2 <> 7:45pm: Matt Heath from Monzo - "Mistakes were made — Modelling prototypes to critical systems with Cassandra" Cassandra provides highly scalable resilient data storage for a variety of needs, but its effectiveness is often limited by the way we model our data, design schemas, and determine usage patterns. In this talk Matt will look at some of the design patterns Monzo have adopted and developed, from the prototype stage, to their highly scalable core banking systems. // Speaker 3 <> 8:15pm: Cedrick will talk about "Building API for Cassandra Applications : REST, gRPC, GraphQL, which one should you pick?" Depending on your use cases you may need to access databases with different patterns: CRUD, commands, Streaming, Batches, Asynchronous, Reactive..). At Datastax, the developer advocates team implements reference applications for developers. We had the chance to implement multiple approaches and can provide feedback. KillrVideo.com is one of this application, it has been written in 3 languages (Java, C# and Node) and implement API with REST, gRPC and GraphQL. Though live session, browsing real code, you will see implementation details, lessons learnt and get working source code in Github as takeaway. _____ Special thanks to Monzo who are hosting, live streaming (link will be published soon!) and providing foods and drinks for this event 🙌 Big thanks to long term Cassandra supporter DataStax (http://www.datastax.com/). DataStax are one of the largest supporters of the Cassandra project and offer comprehensive support as well as their own distribution of Cassandra, Spark and Solr (DataStax Enterprise).

  • Patrick McFadin and Carlos Alonso - SMACK & Data Modelling

    Skills Matter - CodeNode

    ***Please Register Here for access to the building & free beer on the day!*** (https://skillsmatter.com/meetups/7880-smack-and-data-modelling) Agenda: 6:30-7:00pm : Reception (pizza and drinks) 7:00-7:45pm: Carlos Alonso - Scalable data modelling by example 7:45-8:30pm: Patrick McFadin - Laying down the SMACK on your data pipelines ---- Speaker: Carlos Alonso Bio: Carlos received his Masters CS at Salamanca University, Spain. He worked his first 5 career years there in a digital agency, gaining expertise on a very wide range of technologies from backend to iOS/web front end before moving to London to work as a Software Engineer at MyDrive Solutions where he does all kinds of data related stuff. He enjoys lecturing, mentoring and speaking in conferences, like the last Cassandra Summit where he was awarded with the Cassandra MVP of the year and he got officially certified as a Cassandra Developer. On his spare time he loves volunteering and getting involved in OpenSource and OpenData initiatives. Twitter handle: @calonso Title: Scalable data modelling by example Abstract: Cassandra is getting more and more buzz and that means two things, more development and more issues. Some issues are unavoidable, but some of them are, just by understanding how our tooling works. In this talk I'd like to review the core concepts on which Cassandra is built and how they impose the way we should work with it using some examples that will hopefully give you both a 'Quick Reference' and a 'Checklist' to go through every time you want to build scalable data models. ----- Speaker: Patrick McFadin Lead Evangelist, DataStax Bio: Patrick McFadin is one of the leading experts of Apache Cassandra and data modeling techniques. As the Chief Evangelist for Apache Cassandra and consultant for DataStax, he has helped build some of the largest and exciting deployments in production. Previous to DataStax, he was Chief Architect at Hobsons, an education services company. There, he spoke often on Web Application design and performance. Title: Laying down the SMACK on your data pipelines Abstract: You’ve heard all of the hype, but how can SMACK work for you? In this all-star lineup, you will learn how to create a reactive, scaling, resilient and performant data processing powerhouse. We will go through the basics of Akka, Kafka and Mesos and then deep dive into putting them together in an end2end (and back again) distrubuted transaction. Distributed transactions mean producers waiting for one or more of consumers to respond. On the backend, you will see how Apache Cassandra and Spark can be combined to add the incredibly scaling storage and data analysis needed for fast data pipelines. With these technologies as a foundation, you have the assurance that scale is never a problem and uptime is default. ---- In addition to the talks there will be, as usual, plenty of opportunity to meet other Cassandra users and enjoy robust discussions around NoSQL.

He tweets as @tlberglund, blogs very occasionally at http://timberglund.com (http://timberglund.com/), and lives in Littleton, CO, USA with the wife of his youth and their youngest child. Title: Building Java Applications with Cassandra Abstract: So you’re a JVM developer, you understand Cassandra’s architecture, and you’re on your way to knowing its data model well enough to build descriptive data models that perform well. What you need now is to know the Java Driver. What seems like an inconsequential library that proxies your application’s queries to your Cassandra cluster is actually a sophisticated piece of code that solves a lot of problems for you that early Cassandra developers had to code by hand. Come to this session to see features you might be missing and examples of how to use the Java driver in real applications. ---- DuyHai Doan Bio: DuyHai Doan is a Cassandra technical advocate at DataStax. He spends his time between technical presentations/meetups on Cassandra, coding on open source projects to support the community and helping all companies using Cassandra to make their project successful. Previously he was working as a freelance Java/Cassandra consultant. Title: Cassandra UDF and Materialised Views in depth Abstract: Cassandra is evolving at a very fast pace and keeps introducing new features that close the gap with traditional SQL world, but they are always designed with a distributed approach in mind. First we'll throw an eye at the recent user-defined functions and show how they can improve your application performance and enrich your analytics use-cases. Next, a tour on the materialised views, a major improvement that drastically changes the way people model data in Cassandra and makes developers' life easier! The talk will focus on technical deep-dive and caveats to avoid ---- Speaker: Aaron Morton Bio: Aaron Morton is the Co Founder & Principal Consultant at The Last Pickle (thelastpickle.com (http://thelastpickle.com/)). A professional services company that works with clients to deliver and improve Apache Cassandra based solutions. He's based in New Zealand, is an Apache Cassandra Committer and a DataStax MVP for Apache Cassandra. Title: Lightening Talk: Introduction to Incremental Repair Abstract: Repair has long been a pain point for running a Cassandra cluster. Cassandra 2.1 took steps to make it less painful by adding Incremental Repairs, which aim to reduce the amount of work needed to keep data fully distributed. In this talk Aaron Morton, Team Member at The Last Pickle and Cassandra Committer, will discuss why we have repair, what it does, and how Incremental Repair plans to make it better. ---- In addition to the talks there will be, as usual, plenty of opportunity to meet other Cassandra users and enjoy robust discussions around NoSQL.
