How To Install Judy on Fedora 34
Introduction
In this tutorial we learn how to install Judy on Fedora 34.
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 34. In this tutorial we discuss both methods but you only need to choose one of method to install Judy.
Install Judy on Fedora 34 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
Fedora 34 - x86_64 20 kB/s | 6.6 kB 00:00
Fedora 34 openh264 (From Cisco) - x86_64 1.4 kB/s | 989 B 00:00
Fedora Modular 34 - x86_64 68 kB/s | 6.5 kB 00:00
Fedora 34 - x86_64 - Updates 3.5 kB/s | 6.2 kB 00:01
Fedora Modular 34 - x86_64 - Updates 17 kB/s | 5.9 kB 00:00
Metadata cache created.
After updating yum database, We can install Judy using dnf by running the following command:
sudo dnf -y install Judy
