DuckDB behind the magic : Parsing the Unparseable CSVs

DuckDB is fast, there's no doubt about it, right? But a lot of work is being done to make our solution even more robust and reliable in data reading and ingestion. Who hasn't had to deal with a CSV file with corrupted or incorrectly formatted lines? A series of improvements have been implemented on how DuckDB detects and manages formatting errors in our datasets. Pedro Holanda and Mehdi Quazza bring the latest in a relaxed and practical conversation.

CMU 15-721 - DuckDB: Advanced Database Systems

Andy Pavlo provided a comprehensive overview of DuckDB and a detailed discussion on the internal workings of DuckDB, such as its execution model, vectorized query processing, and handling of data storage and retrieval. This includes how DuckDB processes queries and utilizes hardware efficiently, ensuring fast response times for analytical queries.

duckplyr: dplyr powered by DuckDB

If you work with R, you need to try the 'duckplyr' package. It integrates the efficiency of DuckDB with the familiar functionalities of dplyr. 'Duckplyr' enables data analysts to perform complex transformations directly on their data frames, significantly improving performance without leaving the familiar dplyr environment. This represents a considerable advantage for daily R users, as it combines ease of use with powerful data processing capabilities.

Managing raster (Satellite Imagery) in DuckDB with the spatial extension

The possibilities with DuckDB are vast and continue to expand. Alvaro Huarte delves into the integration of geospatial images with DuckDB's spatial extension in detail. As spatial analysis has become essential in various fields, from geographic information systems (GIS) to urban planning and beyond, this integration offers new possibilities for such analyses and has been gaining significant momentum in our community.

How Fast can Python Parse 1 Billion Rows of Data?

No spoilers please. But can you guess which Python implementation performed the best? The 1 billion line challenge provides an opportunity to investigate how efficiently we can process a large text file and obtain some general statistics. This video explores the most effective strategies for processing lines using both pure Python and external libraries. Are you surprised by the result?

Using DuckDB JupySQL and Pandas in a notebook

Fly high with the full potential of your Jupyter Notebooks using DuckDB! In this article, Deepa Vasanthkumar demonstrates how integrating these powerful tools enhances your data analysis experience with fast querying and robust data manipulation. Ideal for efficiently handling large datasets, this combination ensures you never compromise on performance or flexibility. Learn the simple steps to take flight and elevate your data skills.

PyIceberg as a solution to Multi-engine data stack

PyIceberg could be the solution you've been looking for to integrate DuckDB with Snowflake. In this article, Julien Hurault presents a step-by-step guide to building a 'multi-engine data stack' that combines Snowflake, DuckDB, and Iceberg, offering efficiency, scalability, and integration between these two platforms. While Iceberg is still in its early stages, enabling interoperability among different engines opens up so many possibilities.

A portable Data Analytics stack using Docker, Mage, dbt-core, DuckDB and Superset

Who else loves testing out new technologies and exploring them through tutorials and end-to-end projects? If you're like me, check out this project exploring the creation of a complete data stack. It leverages technologies like Mage, DuckDB, dbt core, and Superset to provide a comprehensive solution. It's a fantastic starting point for demos, templates, or learning how all these components work together. Have fun!

Orchestrating data quality with Soda, Motherduck and Prefect

This month, our page is full of end-to-end projects, with a highlight now on building a data quality pipeline. If the topic of data quality keeps you up at night, check out this solution that integrates Prefect, Soda, MotherDuck, and YData Profiling. With YData Profiling providing exploratory analysis and Soda performing accurate checks, you can get back to having a peaceful night's sleep.

File-based Postgres Analytics with DuckDB and AWS S3

If you're looking for a practical introduction to using Supabase storage, this video is for you! With clear, step-by-step demonstrations, you'll learn how to connect DuckDB to your PostgreSQL database in Supabase, export data to storage buckets, and perform analyses directly on the files.
