Judy Libraries
The Judy product is a C language library that enables an unbounded array capability.
Judy Libraries provide a state-of-the-art core technology that replaces many traditional
data structions and algorithms (such as arrays, sparse arrays, hash tables, B-trees,
binary trees, linear lists, skip lists, and counting functions).

The Judy product delivers:
• Very easy-to-use API
• Improved overall performance and better memory management
• Scalable arrays that can grow dynamically to very large populations while
maintaining excellent performance
Judy offers three types of arrays:
Judy1 functions provide a way to store, retrieve, and locate Boolean values (bit
maps) in a Judy array.
JudyL functions provide a way to store, retrieve, and locate long-word values in a
Judy array.
JudySL functions provide a way to store, retrieve, and locate strings as indexes
(similar to associative arrays in awk, Perl, and Java).
