Following the relational algebra and inspired by the design of dplyr, Arquero provides a fluent API for manipulating column-oriented data frames. Arquero supports a range of data transformation tasks, including filter, sample, aggregation, window, join, and reshaping operations. Fast: process data tables with million+ rows. Flexible: query over arrays, typed arrays, array-like objects, or Apache Arrow columns. Full-Featured: perform a variety of wrangling and analysis tasks. Extensible: add new column types or functions, including aggregate & window operations. Lightweight: small size, minimal dependencies. To get up and running, start with the Introducing Arquero tutorial, part of the Arquero notebook collection. Have a question or need help? Visit the Arquero GitHub repo or post to the Arquero GitHub Discussions board.
