AWSreInvent #AWSreInvent2024

🌟 Session Overview 🌟

Session Name: Maximising Cassandra's Potential: Tips on Schema, Queries, Parallel Access, and Reactive Programming Speaker: Hartmut Armbruster Session Description: In this talk, we will design the backend and data layer for a data-rich social platform feed tailored to authenticated users.

We will begin with UI wireframes and then develop logical and physical Cassandra data models and query patterns. Using reactive programming paradigms, we will optimize the process flow to efficiently execute queries in parallel.

Finally, we will implement a Proof of Concept (POC) using Kotlin, Quarkus, and Mutiny. While reactive programming can initially seem intimidating, it becomes productive, elegant, and even enjoyable once you become familiar with it.

This talk aims to inspire new ideas and showcase what’s possible with a modern, tailored, and efficiently utilized stack.

Prior knowledge of Cassandra Query Language (CQL), data partitioning/sharding concepts, and reactive programming is beneficial but optional.

Interview

Introduction How did you get involved in the area of data management? For anyone who isn’t familiar with Cassandra, can you briefly describe what it is and some of the story behind it?

How did you get involved in the Cassandra project and how would you characterize your role?

What are the main use cases and industries where someone is likely to use Cassandra? What is notable about the version 4 release?

What were some of the factors that contributed to the long delay between versions 3 and 4? (2015 – 2021) What are your thoughts on the ongoing utility/benefits of projects such as ScyllaDB, particularly in light of the most recent release?

Cassandra is primarily used as a system of record. What are some of the tools and system architectures that users turn to when building analytical workloads for data stored in Cassandra? The architecture of Cassandra has lent itself well to the cloud native ecosystem that has been growing in recent years. What do you see as the opportunities for Cassandra over the near to medium term as the cloud continues to grow in prominence?

Summary Everyone expects data to be transmitted, processed, and updated instantly as more and more products integrate streaming data. The technology to make that possible has been around for a number of years, but the barriers to adoption have still been high due to the level of technical understanding and operational capacity that have been required to run at scale. Datastax has recently introduced a new managed offering for Pulsar workloads in the form of Astra Streaming that lowers those barriers and make stremaing workloads accessible to a wider audience. In this episode Prabhat Jha and Jonathan Ellis share the work that they have been doing to integrate streaming data into their managed Cassandra service. They explain how Pulsar is being used by their customers, the work that they have done to scale the administrative workload for multi-tenant environments, and the challenges of operating such a data intensive service at large scale. This is a fascinating conversation with a lot of useful lessons for anyone who wants to understand the operational aspects of Pulsar and the benefits that it can provide to data workloads.

Summary A majority of the time spent in data engineering is copying data between systems to make the information available for different purposes. This introduces challenges such as keeping information synchronized, managing schema evolution, building transformations to match the expectations of the destination systems. H.O. Maycotte was faced with these same challenges but at a massive scale, leading him to question if there is a better way. After tasking some of his top engineers to consider the problem in a new light they created the Pilosa engine. In this episode H.O. explains how using Pilosa as the core he built the Molecula platform to eliminate the need to copy data between systems in able to make it accessible for analytical and machine learning purposes. He also discusses the challenges that he faces in helping potential users and customers understand the shift in thinking that this creates, and how the system is architected to make it possible. This is a fascinating conversation about what the future looks like when you revisit your assumptions about how systems are designed.

Why is that important and how does it work in Yugabyte? What are the caveats?What are the most notable features of YugabyteDB that would lead someone to choose it over any of the myriad other options? What are the use cases that it is uniquely suited to?What are some of the systems or architecture patterns that can be replaced with Yugabyte?How does the design of Yugabyte or the different ways it is being used influence the way that users should think about modeling their data?Yugabyte is an impressive piece of engineering. Can you talk through the major design elements and how it is implemented?Easy scaling and failover is a feature that many database engines would like to be able to claim. What are the difficult elements that prevent them from implementing that capability as a standard practice? What do you have to sacrifice in order to support the level of scale and fault tolerance that you provide?Speaking of scaling, there are many ways to define that term, from vertical scaling of storage or compute, to horizontal scaling of compute, to scaling of reads and writes. What are the primary scaling factors that you focus on in Yugabyte?How do you approach testing and validation of the code given the complexity of the system that you are building?In terms of the query API you have support for a Postgres compatible SQL dialect as well as a Cassandra based syntax. What are the benefits of targeting compatibility with those platforms? What are the challenges and benefits of maintaining compatibility with those other platforms?Can you describe how the storage layer is implemented and the division between the different query formats?What are the operational characteristics of YugabyteDB? What are the complexities or edge cases that users should be aware of when planning a deployment?One of the challenges of working with large volumes of data is creating and maintaining backups. How does Yugabyte handle that problem?Most open source infrastructure projects that are backed by a business withhold various "enterprise" features such as backups and change data capture as a means of driving revenue. Can you talk through your motivation for releasing those capabilities as open source?What is the business model that you are using for YugabyteDB and how does it differ from the tribal knowledge of how open source companies generally work?What are some of the most interesting, innovative, or unexpected ways that you have seen yugabyte used?When is Yugabyte the wrong choice?What do you have planned for the future of the technical and business aspects of Yugabyte?Contact Info @karthikr on TwitterLinkedInrkarthik007 on GitHubParting Question From your perspective, what is the biggest gap in the tooling or technology for data management today?Closing Announcements Thank you for listening!

Your host is Tobias Macey and today I’m interviewing Vadim Semenov about how data engineers work at DataDog

Interview

Introduction How did you get involved in the area of data management? For anyone who isn’t familiar with DataDog, can you start by describing the types and volumes of data that you’re dealing with? What are the main components of your platform for managing that information? How are the data teams at DataDog organized and what are your primary responsibilities in the organization? What are some of the complexities and challenges that you face in your work as a result of the volume of data that you are processing?

What are some of the strategies which have proven to be most useful in overcoming those challenges?

Who are the main consumers of your work and how do you build in feedback cycles to ensure that their needs are being met? Given that the majority of the data being ingested by DataDog is timeseries, what are your lifecycle and retention policies for that information? Most of the data that you are working with is customer generated from your deployed agents and API integrations. How do you manage cleanliness and schema enforcement for the events as they are being delivered? What are some of the upcoming projects that you have planned for the upcoming months and years? What are some of the technologies, patterns, or practices that you are hoping to adopt?

Summary Anomaly detection is a capability that is useful in a variety of problem domains, including finance, internet of things, and systems monitoring. Scaling the volume of events that can be processed in real-time can be challenging, so Paul Brebner from Instaclustr set out to see how far he could push Kafka and Cassandra for this use case. In this interview he explains the system design that he tested, his findings for how these tools were able to work together, and how they behaved at different orders of scale. It was an interesting conversation about how he stress tested the Instaclustr managed service for benchmarking an application that has real-world utility.

And don’t forget to thank them for their continued support of this show! Integrating data across the enterprise has been around for decades – so have the techniques to do it. But, a new way of integrating data and improving streams has evolved. By integrating each silo independently – data is able to integrate without any direct relation. At CluedIn they call it “eventual connectivity”. If you want to learn more on how to deliver fast access to your data across the enterprise leveraging this new method, and the technologies that make it possible, get a demo or presentation of the CluedIn Data Hub by visiting dataengineeringpodcast.com/cluedin.
