Serban Teodorescu of Adobe presents “Safe OS/system upgrade by rebooting”
This talk will cover how we implemented an idea presented at an ApacheCon by Netflix. In order to safely upgrade the OS and perform various system upgrades without having to move data around on 900 instances in one week, we had to implement a simple state machine with some puppet and Python scripting. We used DynamoDB for a “cluster lock” and Prometheus for metrics to alert when the process was stuck.
About the Presenter
Serban Teodorescu is an SRE at Adobe, where he’s part of a small team that manages 30+ Cassandra clusters for Adobe Audience Manager. Previously, he was a Python programmer, and he’s still trying to find out how a developer who preferred SQL databases ended up as an SRE for a Cassandra team. Apart from Cassandra and Python, he’s interested in automating his tasks with terraform, AWX, and StackStorm.
Apache Cassandra is an open source NoSQL distributed database trusted by thousands of companies for scalability and high availability without compromising performance. Linear scalability and proven fault tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data.

The Apache Cassandra World Party 2022 was a virtual, one-day celebration on Wednesday, July 20, 2022 held in anticipation of the launch of 4.1

Ryan Wright of thatDot presents “Cassandra-backed Streaming Graph with Quine”
Quine is a "streaming graph" built on Apache Cassandra. This powerful combination is revolutionizing what you can do with event stream processing and how easy it is to make happen. In this lightning talk, you'll see the world's fastest data pipeline built from start to finish: it consumes streaming data and builds it into a graph, stores that graph in Apache Cassandra, and triggers immediate results from graph patterns in real-time. One slide; live code; real results… all in 5 minutes.
About the Presenter
Ryan Wright is the creator of Quine, and has been leading software teams focused on data infrastructure and data science for two decades. He has served as principal engineer, director of engineering, principal investigator on DARPA-funded research programs, and is currently the founder and CEO of thatDot—the company supporting Quine. Ryan particularly enjoys making the philosophical ends of computer science more practical and useful. This usually involves problems related to language, meaning, and data.

Rahul Xavier Singh of Anant presents “Cleaning Large Scale Data in Cassandra”
So you have tons of data in Apache Cassandra. Then you realize years later that you didn't have any TTLs on your data and now there's terabytes or petabytes of data that needs to be cleaned out. We'll cover how we used Apache Airflow, Apache Spark, and some carefully crafted DAGs to democratize data cleanup and other common data operations without giving users access to the Spark Cluster. This pattern can also be used to build other common data operations such as import / export of data to and from Apache Cassandra using a variety of tools including DSBulk, or Scylla Migrator.
About the Presenter
Rahul leads a boutique consultancy that helps clients design, build, and operate global scale platforms that serve and impact large groups of people. He's been working with Cassandra for about 7 years and has been contributing to the community by publishing cassandra.link and running a weekly "Cassandra Lunch" for almost a year. He's recently gotten involved in the Cassandra Kubernetes SIG and helps out by updating the blog with updates.

Aleks Volochnev of DataStax presents “Data Visualisation with Apache Cassandra and Grafana”
Once upon a time, I wanted to visualize my time-series data in a chart. The task seemed simple at first sight: I have Cassandra, and I have Grafana, what can be easier? Quite surprisingly, there were no direct ways to do it, the best advice I got was to migrate all my data to InfluxDB! When a programmer doesn't have an integration, they write the integration! Let me introduce to you my "Cassandra Datasource for Grafana" which gives you a straightforward way to draw charts and plots of your bits and rows, and configure alerts based on your requirements!
About the Presenter
After many years in software development as a developer, technical lead, DevOps engineer, and architect, Aleks focused himself on distributed applications and cloud architecture. Working as a developer advocate at DataStax, he shares his knowledge and expertise in the field of microservices, disaster tolerant systems, and hybrid platforms.

Manish Khandelwal of Ericsson presents “Using SSTable immutability for incremental backup”
This lightning talk will cover the idea where we use the immutability feature of SSTables to perform an incremental backup. The main idea is to copy only those sstables which are new after the first backup was taken.
