- Building an AWS-hosted Data Platform || Design Financial Data Interfaces
Schedule: 6:00 - Doors & Food 6:30 - Talk 1 7:15 - Talk 2 7:45 - Wrap & Chat ********* Talk 1: An Opinionated Guide to Building an AWS-hosted Data Platform Presenters: Tom LeRoux, VP of Data Engineering and Analytics @ Disney Streaming Abstract: These days there are many ways to build a cloud-based data warehouse. While AWS makes it easier to deploy infrastructure, it does not provide a prescriptive way to build out a data and analytics platform that meets the needs of both data producers and data consumers. In this talk we will dive into particular design biases that helped us choose our data architecture for The Walt Disney Company’s direct-to-consumer video businesses globally, including the ESPN+ premium sports streaming service and Disney+, the upcoming Disney subscription video service. We will dig into the different patterns of streaming and batch data ingestions, and talk about how different types of data is transformed and made available to the organization. Bio: Tom LeRoux is VP of Data Engineering at Disney Streaming Services. Tom joined DSS in July of 2018 and runs the data platform that powers Disney+ and ESPN+. Prior to DSS Tom worked at Goldman Sachs where he led the team that built Goldman's new consumer banking data and analytics platform. ********* Talk 2: How to Design and Scale Financial Data Models and Interfaces Presenter: Liwei Mao, Senior Software Engineer @ Button Abstract: Building a financial data store can be hard. You have many users of financial data within a company. There's the finance team, who sends out monthly invoices and makes projections, the marketing team, who uses financial data to gauge the efficiency of campaigns, the analytics team, who integrate financial data to provide company KPIs. And lastly, your company's external users, to whom you promised easy and accurate access to the transactions you process for them. In engineering, we often hear let's have a "single source of truth". It’s easy to mistake that to mean, let’s aim to have a single financial data interface that serves all these users needs! In this talk, we'll detail why that doesn't work. We'll discuss how to design financial data models and interfaces that flexibly and performantly serve user needs while fulfilling the high accuracy requirements for financial data. Lastly, we'll talk about some strategies for scaling and optimizations. Bio: Liwei Mao is a Senior Software Engineer at Button. She loves designing data products, nerding out over databases, and is a firm believer that good data design removes friction in building products.
- Data Validation and Alerting. How does Airflow fit in?
Note: This meetup event is being organized as a special joint effort with the NYC Apache Airflow Meetup group: https://www.meetup.com/NYC-Apache-Airflow-Meetup/events/260257700/ Schedule: 6:00 - Doors & Food 6:30 - Talk 1 7:15 - Talk 2 7:45 - Wrap & Chat Talk 1: Data Validation and Alerting. How does Airflow fit in? Abstract: After your ETL runs, a new kind of fun starts. -Is my output data 'right' compared to my 'source of truth'? -Wait a second, how do I even know if my input data was ok? -How do get alerted if a metric violates some threshold/tolerance or if some dimensional data is messed up? -What if I want alerts to be triggered based on dynamic thresholds? -How hard is it to maintain my checks and alerts? Like everyone else, the New York Time's Data Engineers, Data Analysts and Data Scientists have been wrestling with the above questions. This presentation will cover what the Times has tried and the approach that's been settled on (for now). And yes, Airflow plays an important part. Presenters: Brian Lavery, Data Engineer, New York Times Mariam Melikadze, Manager-Advertising Analytics, New York Times Talk 2: Abstract: Apache Airflow is a Python-based task orchestrator that has seen widespread adoption among startups and enterprises alike to author, schedule, and monitor data workflows. By deploying the Airflow stack via Helm on Kubernetes, fresh environments can be easily spun up or down, scaling to near 0 when no jobs are running. As companies scale up their Airflow usage, they need more control, and observability over their stack as it becomes more ingrained into their culture and more important to the business. This talk will go through the technical challenges of supporting thousands of airflow deployments, how to monitor them, reliably push DAG updates, and how to build all the supporting infrastructure of a rock-solid Airflow system in a cloud native environment using open source software. Presenter: Viraj Parekh, Data Engineer, Astronomer Instructions to follow upon arrival: Enter the lobby on the north side of the building. A representative will be waiting next to one of north end elevator turnstiles with a sign that says 'Airflow Meet-Up'. They will assist you in getting through security and send you up to the 15th floor where another representative will be waiting to direct you to the room.

- Fraud Detection with Apache Kafka and KSQL
Schedule: 6:00 - Doors & Food 6:30 - Talk 1 7:15 - Wrap & Chat Talk 1: ATM Fraud Detection with Apache Kafka and KSQL Speaker: Robin Moffatt, Developer Advocate @ Confluent Abstract: Detecting fraudulent activity in real time can save a business significant amounts of money, but has traditionally been an area requiring a lot of complex programming and frameworks, particularly at scale. Using KSQL, it's possible to use just SQL to build scalable real-time applications. In this talk, we'll look at what KSQL is, and how its ability to join streams of events can be used to detect possibly fraudulent activity based on a stream of ATM transactions. We'll also see how easy it is to integrate Kafka with other systems—both upstream and downstream—using Kafka Connect to stream from a database into Kafka, and from Kafka into Elasticsearch. Bio: Robin is a Developer Advocate at Confluent, the company founded by the original creators of Apache Kafka®, as well as an Oracle Groundbreaker Ambassador and ACE Director (alumnus). His career has always involved data, from the old worlds of COBOL and DB2, through the worlds of Oracle and Hadoop, and into the current world with Kafka. His particular interests are analytics, systems architecture, performance testing and optimization. He blogs at http://cnfl.io/rmoff and http://rmoff.net/ (and previously http://ritt.md/rmoff) and can be found tweeting grumpy geek thoughts as @rmoff. Outside of work he enjoys drinking good beer and eating fried breakfasts, although generally not at the same time.
- Beyond Data Engineering: Careers in AI + DevOps
*This is a joint event with Insight Tech Talks Meetup Group: https://www.meetup.com/insight-tech-talks/events/259516414/ Schedule: 6:00 - Doors & Food 6:30 - Talk 1 7:15 - Talk 2 7:45 - Wrap & Chat Talk 1: Lessons from Building and Deploying AI Systems Speaker: Chuck Yee, ML Research Engineer @ Bloomberg Abstract: AI has experienced unprecedented hype over the past seven years, but what is the reality of applied AI within a business ecosystem? In this talk, I’ll be sharing stories of success and failure building and deploying AI systems, and personal observations from my time in the industry. Bio: Chuck-Hou is an Insight Fellow who recently joined Bloomberg’s NLP team after gaining experience building deep learning models for x-ray interpretation at Imagen Technologies. Talk 2: CICD From the Ground Up Speaker: Max McKittrick, Data Engineer, ECI @ Capital One Abstract: At Capital One, the ECI team manages a clickstream application and pipeline durability is a critical consideration. In this talk, I want to discuss our lessons learned and how we have improved our CICD practices over the past few months.

He received his MS from the University of Illinois and worked as a researcher and data consultant prior to attending Insight.
- Containerizing Data Workflow and Testing Data Pipelines
Schedule: 6:00 - Doors & Food 6:30 - Talk 1 7:15 - Talk 2 7:45 - Wrap & Chat Talk 1: Pros and cons of containerizing data workflows (and how to have the best of both worlds) Speaker: Tian Xie, Data Engineer @ Enigma Abstract: At Enigma, we run over one hundred workflows to ingest public data into our system. Running so many workflows also means managing dependencies and deployment for each of those workflows. Over time, we have iterated over several solutions to this problem and this is our story. Spoiler: docker is involved, but (*plot twist*) it only leads to another set of problems in the 2nd act. Bio: Tian Xie has been working in the NYC tech start-up scene for the last eight years on consumer video rendering, on-demand shipping, and now data engineering at Enigma Technologies. Talk 2: Building a Data Pipeline with Testing in Mind Speaker: Jiaqi Liu, Software Engineer @ Button, Inc Abstract: It’s one thing to build a robust data pipeline process in python but a whole other challenge to find tooling and build out the framework that allows for testing a data process. In order to truly iterate and develop a codebase, one has to be able to confidently test during the development process and monitor the production system. In this talk, I hope to address the key components for building out end to end testing for data pipelines by borrowing concepts from how we test python web services. Just like how we want to check for healthy status codes from our API responses, we want to be able to check that a pipeline is working as expected given the correct inputs. We’ll talk about key features that allows a data pipeline to be easily testable and how to identify timeseries metrics that can be used to monitor the health of a data pipeline.
- Monitoring in Google Cloud Dataflow || AWS Lambda Best Practices
Schedule: 6:00 - Doors & Food 6:30 - Talk 1 7:15 - Talk 2 7:45 - Wrap & Chat **Talk 1: Monitoring and Measuring Performance in Google Cloud's Dataflow** Speaker: Leigh Pember, Google Cloud Customer Engineer @Google Abstract: This intermediate-level session will dive into some of the different ways to measure, monitor and debug performance when running Dataflow jobs in Google Cloud. The session will primarily be centered around a demo and some of the insights will be applicable to open source Apache Beam whereas others will be more specific to GCP Dataflow. I put together this presentation based on lessons learned from debugging Dataflow with a GCP gaming/media customer, but the demo and examples should be generally applicable to anyone running these jobs in the cloud. Some high level topics will include important metrics and their meaning, logging, pipeline code optimization and infrastructure resource utilization. **Talk 2: Best Practices and Container reuse in AWS Lambda** *Speaker:* Angela Razzell, Senior Software Engineer @ Capital One *Abstract:* AWS Lambda’s Functions-as-a-Service (FaaS) saves developer time by removing the need to manage infrastructure and scaling. During this talk, Angela will demonstrate the powers and pitfalls of setting up your lambdas the right way. By following these best practices in your code, you can improve the running time and efficiencies of lambda functions. Connecting to other services such as databases are expensive operations and handling these tasks correctly can shave the execution time to a fraction of the cold start value - especially valuable in a real-time context. Angela Razzell is a Senior Data Engineer at Capital One, currently working on a messaging application in Retail Direct Bank.

- Abstracted Interfaces for Domain-driven Dev & Geospatial Data Analytics in Spark
Schedule: 6:00 - Doors & Food 6:30 - Talk 1 7:15 - Talk 2 8:00 - Wrap & Chat **Talk 1: Abstracted Interfaces for Domain-driven Development** Speaker: Soren Larson, Data Scientist & AI Engineer Abstract: Abstraction is ever increasing. Services we used to have to build and maintain in low level languages are now abstracted into the cloud with sturdy SLAs and frameworks accommodating of most our use cases. Stakeholders are changing. With enterprise interfaces becoming more consumer oriented in their outlook and design, stakeholders and even users of these interfaces can reasonably be without some of the skills previously needed to shape and manage large pieces of data. With fewer resources needed to spin up a reliable and powerful big data system, we can spend more time on nuance of data manipulation and offer interfaces to nontechnical stakeholders more expressive than before, with performance secured by the guardrails of our increasingly sturdy infrastructure. I'll talk about one type of interface I've found success with, and what enterprise b2b design might say about the future of data engineering. **Talk 2: Using Spark for real time telemetry and geospatial data analytics at scale** Speaker: Dillon Bostwick, Solutions Engineer @ Databricks Abstract: We will use public NYC neighborhood data sitting on Azure Blob Storage and telemetry streams from Azure Event Hubs to analyze routes through NYC. This will open up discussion on how the Magellan geospatial analytics library uses Spark’s catalyst optimizer to conduct spatial joins, as well as how we can use Databricks Delta to improve performance as we build an optimized real time pipeline at scale. Finally we will discuss how we can leverage Azure Databricks to move the application from development to production. Technologies discussed: Azure Blob Storage, Azure Event Hubs, Azure Databricks, Magellan, Spark Catalyst optimizer, Spark Structured Streaming, Databricks Delta
