How To Install Judy on Fedora 36

In this tutorial we learn how to install Judy in Fedora 36. Judy is General purpose dynamic array

Introduction

In this tutorial we learn how to install Judy on Fedora 36.

What is Judy

Judy is a C library that provides a state-of-the-art core technology that implements a sparse dynamic array. Judy arrays are declared simply with a null pointer. A Judy array consumes memory only when it is populated, yet can grow to take advantage of all available memory if desired. Judy’s key benefits are scalability, high performance, and memory efficiency. A Judy array is extensible and can scale up to a very large number of elements, bounded only by machine memory. Since Judy is designed as an unbounded array, the size of a Judy array is not pre-allocated but grows and shrinks dynamically with the array population.

We can use yum or dnf to install Judy on Fedora 36. In this tutorial we discuss both methods but you only need to choose one of method to install Judy.

Install Judy on Fedora 36 Using dnf

sudo dnf makecache --refresh

After updating yum database, We can install Judy using dnf by running the following command:

sudo dnf -y install Judy
