Polars is a DataFrames library built in Rust with bindings for Python and Node.js. It uses Apache Arrow's columnar format as its memory model. DuckDB can read Polars DataFrames and convert query results to Polars DataFrames. It does this internally using the efficient Apache Arrow integration. Note that the pyarrow library must be installed for the integration to work. Installation pip install -U duckdb 'polars[pyarrow]' Polars to DuckDB DuckDB can natively query Polars DataFrames by referrin...| DuckDB

In this article, I'll describe how I implemented German string and the challenges of doing so in Rust. Specifically, I'll examine how to enable shared ownership for such data structure. Providing unique ownership is relatively trivial, and there is already a nicely written tutorial from the Rustonomicon teaching you how to [implement a `Vec`], which is not much different from a `String`. But first, let's talk about the concept of German string.| ltungv

Many data processing systems have adapted our custom string format. Find out what makes it so special and why it is so relevant to them.| CedarDB - The All-In-One-Database
Apache Arrow is a technology widely adopted in big data, analytics, and machine learning applications. In this article, we share F5’s experience with Arrow, specifically its application to telemetry, and the challenges we encountered while optimizing the OpenTelemetry protocol to significantly reduce bandwidth costs. The promising results we achieved inspired us to share our insights. This article specifically focuses on transforming relatively complex data structure from various formats in...| Apache Arrow
