Summary

Building a database engine requires a substantial amount of engineering effort and time investment. Over the decades of research and development into building these software systems there are a number of common components that are shared across implementations. When Paul Dix decided to re-write the InfluxDB engine he found the Apache Arrow ecosystem ready and waiting with useful building blocks to accelerate the process. In this episode he explains how he used the combination of Apache Arrow, Flight, Datafusion, and Parquet to lay the foundation of the newest version of his time-series database.

Interview

Introduction How did you get involved in the area of data management? Can you start by describing the FDAP stack and how the components combine to provide a foundational architecture for database engines?

This was the core of your recent re-write of the InfluxDB engine. What were the design goals and constraints that led you to this architecture?

Each of the architectural components are well engineered for their particular scope. What is the engineering work that is involved in building a cohesive platform from those components? One of the major benefits of using open source components is the network effect of ecosystem integrations. That can also be a risk when the community vision for the project doesn't align with your own goals. How have you worked to mitigate that risk in your specific platform? Can you describe the

Making Moves with Arrow Data: Introducing Arrow Database Connectivity (ADBC) | Voltron Data

ABOUT THE TALK: In this talk, we'll dive into one of the newest Apache Arrow subprojects, Arrow Database Connectivity (ADBC), an API specification for Arrow-based database access.

Over the course of this session, you’ll get a crash course in ADBC and learn how it communicates with different data APIs (like Arrow Flight SQL and Postgres) using Arrow-native in-memory data. By the end, you’ll understand the use cases it can conquer and know where to access the resources you need to get started.

This talk will cover goals, use-cases, and examples of using ADBC to communicate with different Data APIs (such as Flight SQL or postgres) with Arrow Native in-memory data.

ABOUT THE SPEAKER: Matthew Topol is a committer for the Apache Arrow project, frequently enhancing the Golang Arrow and Parquet libraries among other enhancements and helping to grow the Arrow Community. Recently, Matt has joined Voltron Data in order to work on the Apache Arrow libraries full time and grow the Arrow Golang community. In June 2022, Matt's first book was published, which is the first (and currently only) book on Apache Arrow titled "In-Memory Analytics with Apache Arrow".

Apache Arrow is a multi-language toolbox for accelerated data interchange and in-memory processing, and is becoming the de facto standard for tabular data. This talk will give an overview of the recent developments both in Apache Arrow itself as how it is being adopted in the PyData ecosystem (and beyond) and can improve your day-to-day data analytics workflows.

In this talk, we will report on our experiences switching from Pandas to Polars in a real-world ML project. Polars is a new high-performance dataframe library for Python based on Apache Arrow and written in Rust. We will compare the performance of polars with the popular pandas library, and show how polars can provide significant speed improvements for data manipulation and analysis tasks. We will also discuss the unique features of polars, such as its ability to handle large datasets that do not fit into memory, and how it feels in practice to make the switch from Pandas. This talk is aimed at data scientists, analysts, and anyone interested in fast and efficient data processing in Python.

Pandas is the de-facto standard for data manipulation in python, which I personally love for its flexible syntax and interoperability. But Pandas has well-known drawbacks such as memory in-efficiency, inconsistent missing data handling and lacking multicore-support. Multiple open-source projects aim to solve those issues, the most interesting is Polars.

Polars uses Rust and Apache Arrow to win in all kinds of performance-benchmarks and evolves fast. But is it already stable enough to migrate an existing Pandas' codebase? And does it meet the high-expectations on query language flexibility of long-time Pandas-lovers?

In this talk, I will explain, how Polars can be that fast, and present my insights on where Polars shines and in which scenarios I stay with pandas (at least for now!)

Summary

Business intelligence has gone through many generational shifts, but each generation has largely maintained the same workflow. Data analysts create reports that are used by the business to understand and direct the business, but the process is very labor and time intensive. The team at Omni have taken a new approach by automatically building models based on the queries that are executed. In this episode Chris Merrick shares how they manage integration and automation around the modeling layer and how it improves the organizational experience of business intelligence.

Apache Arrow Flight SQL: High Performance, Simplicity, and Interoperability for Data Transfers

Network protocols for transferring data generally have one of two problems: they’re slow for large data transfers but have simple APIs (e.g. JDBC) or they’re fast for large data transfers but have complex APIs specific to the system. Apache Arrow Flight addresses the former by providing high performance data transfers and half of the latter by having a standard API independent of systems. However, while the Arrow Flight API is performant and an open standard, it can be more complex to use than simpler APIs like JDBC.

Arrow Flight SQL rounds out the solution, providing both great performance and a simple universal API.

In this talk, we’ll show the performance benefits of Arrow Flight, the client difference between interacting with Arrow Flight and Arrow Flight SQL, and an overview of a JDBC driver built on Arrow Flight SQL, enabling clients to take advantage of this increased performance with zero application changes.

Summary Pandas is a powerful tool for cleaning, transforming, manipulating, or enriching data, among many other potential uses. As a result it has become a standard tool for data engineers for a wide range of applications. Matt Harrison is a Python expert with a long history of working with data who now spends his time on consulting and training. He recently wrote a book on effective patterns for Pandas code, and in this episode he shares advice on how to write efficient data processing routines that will scale with your data volumes, while being understandable and maintainable.

Introduction How did you get involved in the area of data management? What are the main tasks that you have seen Pandas used for in a data engineering context? What are some of the common mistakes that can lead to poor performance when scaling to large data sets? What are some of the utility features that you have found most helpful for data processing? One of the interesting add-ons to Pandas is its integration with Arrow. What are some of the considerations for how and when to use the Arrow capabilities vs. out-of-the-box Pandas? Pandas is a tool that spans data processing and data science. What are some of the ways that data engineers should think about writing their code to make it accessible to data scientists for supporting collaboration across data workflows? Pandas is often used for transformation logic. What are some of the ways that engineers should approach the design of their code to make it understandable and maint
