Catch ’em All: Efficient Massive Tabular Data Handling with Tablecloth by Mey Beisaron

March 22, 2023


In this tech talk, we will explore the Clojure library Tablecloth and dive deep into its main data structures, namely dataset and columns.
We will examine the implementation behind these data structures and explore how this library achieves efficient massive tabular data handling while maintaining a simple and user-friendly API.

To make things more fun, (who doesn’t want to have fun?) we will be using Pokémon data sets as examples throughout the talk. We will start by introducing the dataset data structure, which is used to represent a collection of rows and columns. We will discuss how Tablecloth’s dataset is implemented to support a wide range of operations such as filtering, sorting, and grouping, all while maintaining high performance and memory efficiency.
Next, we will dive into the columns data structure, which represents a single column in a dataset. We will examine the column’s internal representation, which allows for flexible and efficient operations such as selecting, transforming, and aggregating values.

By the end of this talk, you will have a deeper understanding of how Tablecloth works and how it can help you handle large and complex data sets with ease. Whether you are a seasoned Clojure developer or just getting started with the language, you won’t want to miss this opportunity to catch ’em all with Tablecloth!
