The Modern Data Stack has brought a lot of new buzzwords into the data engineering lexicon: "data mesh", "data observability", "reverse ETL", "data lineage", "analytics engineering". In this light-hearted talk we will demystify the evolving revolution that will define the future of data analytics & engineering teams.

Our journey begins with the PyData Stack: pandas pipelines powering ETL workflows...clean code, tested code, data validation, perfect for in-memory workflows. As demand for self-serve analytics grows, new data sources bring more APIs to model, more code to maintain, DAG workflow orchestration tools, new nuances to capture ("the tax team defines revenue differently"), more dashboards, more not-quite-bugs ("but my number says this...").

This data maturity journey is a well-trodden path with common pitfalls & opportunities. After dashboards comes predictive modelling ("what will happen"), prescriptive modelling ("what should we do?"), perhaps eventually automated decision making. Getting there is much easier with the advent of the Python Powered Modern Data Stack.

In this talk, we will cover the shift from ETL to ELT, the open-source Modern Data Stack tools you should know, with a focus on how dbt's new Python integration is changing how data pipelines are built, run, tested & maintained. By understanding the latest trends & buzzwords, attendees will gain a deeper insight into Python's role at the core of the future of data engineering.

Tired of having to handle asynchronous processes for neuroevolution? Do you want to leverage massive vectorization and high-throughput accelerators for evolution strategies (ES)? evosax allows you to leverage JAX, XLA compilation and auto-vectorization/parallelization to scale ES to your favorite accelerators. In this talk we will get to know the core API and how to solve distributed black-box optimization problems with evolution strategies.

Asynchronous programming is a type of parallel programming in which a unit of work is allowed to run separately from the primary application thread. Post execution, it notifies the main thread about the completion or failure of the worker thread. There are numerous benefits to using it, such as improved application performance, enhanced responsiveness, and effective usage of CPU.

Asynchronicity seems to be a big reason why Node.js is so popular for server-side programming. Most of the code we write, especially in heavy IO applications like websites, depends on external resources. This could be anything from a remote database POST API call. As soon as you ask for any of these resources, your code is waiting around for process completion with nothing to do. With asynchronous programming, you allow your code to handle other tasks while waiting for these other resources to respond.

In this session, we are going to talk about asynchronous programming in Python. Its benefits and multiple ways to implement it.

Let’s say you are the ruler of a remote island. For it to succeed and thrive you can’t expect it to be isolated from the world. You need to establish trade routes, offer your products to other islands, and import items from them. Doing this will certainly make your economy grow! We’re not going to talk about land masses or commerce, however, you should think of your application as an island that needs to connect to other applications to succeed. Unfortunately, the sea is treacherous and is not always very consistent, similar to the networks you use to connect your application to the world.

We will explore some techniques and libraries in the Python ecosystem used to make your life easier while dealing with external services. From asynchronicity, caching, testing, and building abstractions on top of the APIs you consume, you will definitely learn some strategies to build your connected application gracefully, and avoid those pesky 2 AM errors that keep you awake.

Get ready to level up your big data processing skills! Join us for an introductory talk on Apache Spark, the distributed computing system used by tech giants like Netflix and Amazon. We'll cover PySpark DataFrames and how to use them. Whether you're a Python developer new to big data or looking to explore new technologies, this talk is for you. You'll gain foundational knowledge about Apache Spark and its capabilities, and learn how to leverage DataFrames and SQL APIs to efficiently process large amounts of data. Don't miss out on this opportunity to up your big data game!

Over the past decade, developers, researchers, and the community have successfully built tens of thousands of data applications using Spark. Since then, use cases and requirements of data applications have evolved: Today, every application, from web services that run in application servers, interactive environments such as notebooks and IDEs, to phones and edge devices such as smart home devices, want to leverage the power of data.

However, Spark's driver architecture is monolithic, running client applications on top of a scheduler, optimizer and analyzer. This architecture makes it hard to address these new requirements: there is no built-in capability to remotely connect to a Spark cluster from languages other than SQL.

Spark Connect introduces a decoupled client-server architecture for Apache Spark that allows remote connectivity to Spark clusters using the DataFrame API and unresolved logical plans as the protocol. The separation between client and server allows Spark and its open ecosystem to be leveraged from everywhere. It can be embedded in modern data applications, in IDEs, Notebooks and programming languages.

This talk highlights how simple it is to connect to Spark using Spark Connect from any data applications or IDEs. We will do a deep dive into the architecture of Spark Connect and give an outlook of how the community can participate in the extension of Spark Connect for new programming languages and frameworks - to bring the power of Spark everywhere.

An exchange of views on fastAPI in practice.

FastAPI is great, it helps many developers create REST APIs based on the OpenAPI standard and run them asynchronously. It has a thriving community and educational documentation.

FastAPI does a great job of getting people started with APIs quickly.

This talk will point out some obstacles and dark spots that I wish we had known about before. In this talk we want to highlight solutions.

In this talk, we will introduce the audience to DoWhy, a library for causal machine-learning (ML). We will introduce typical problems where causal ML can be applied and will specifically do a deep dive on root cause analysis using DoWhy. To do this, we will lay out what typical problem spaces for causal ML look like, what kind of problems we're trying to solve, and then show how to use DoWhy's API to solve these problems. Expect to see a lot of code with a hands-on example. We will close this session by zooming out a bit and also talk about the PyWhy organization governing DoWhy.

AutoML, or automated machine learning, offers the promise of transforming raw data into accurate predictions with minimal human intervention, expertise, and manual experimentation. In this talk, we will introduce AutoGluon, a cutting-edge toolkit that enables AutoML for tabular, multimodal and time series data. AutoGluon emphasizes usability, enabling a wide variety of tasks from regression to time series forecasting and image classification through a unified and intuitive API. We will specifically focus on tasks on tabular and time series tasks where AutoGluon is the current state-of-the-art, and demonstrate how AutoGluon can be used to achieve competitive performance on tabular and time series competition data sets. We will also discuss the techniques used to automatically build and train these models, peeking under the hood of AutoGluon.

In this talk, I'll show how large language models such as GPT-3 complement rather than replace existing machine learning workflows. Initial annotations are gathered from the OpenAI API via zero- or few-shot learning, and then corrected by a human decision maker using an annotation tool. The resulting annotations can then be used to train and evaluate models as normal. This process results in higher accuracy than can be achieved from the OpenAI API alone, with the added benefit that you'll own and control the model for runtime.
