This article discusses a library of stochastic streaming algorithms designed for fast approximate analysis of big data. It highlights the library's ability to handle complex queries efficiently, reducing processing times significantly while maintaining mathematically proven error bounds. Adaptors for various platforms and languages are included to facilitate integration.

This article explores the challenges of performing exact queries on large datasets and introduces data sketches as a solution. Sketches provide approximate answers quickly and efficiently, allowing for scalable data analysis without the need for massive storage. The piece outlines how these probabilistic structures work and their advantages in handling big data.

This article explores the evolving role of data engineers over the past 50 years, highlighting their often unnoticed contributions to data infrastructure. It discusses the challenges they face, such as managing dependencies and schema changes, while emphasizing that the core problems remain unchanged despite new tools and technologies.

DuckDB has proven to be superior to Polars when handling large datasets, particularly 1TB of data. While DuckDB effectively manages memory and execution with a robust design, Polars struggles with large data processing, leading to out-of-memory errors.
