Example uses of Judy trees

Question

I was reading about Judy trees. What are some examples of real world usage and comparisons to other data structures?

Answer 1

Judy arrays in Python: http://www.dalkescientific.com/Python/PyJudy.html

Some Examples uses.

PyJudy arrays are similar to Python dictionaries and sets. The primary difference is that PyJudy keys are sorted; by unsigned value if an integer, byte ordering if a string and object id if a Python object. In addition to wrapping the underlying Judy functions, PyJudy implements a subset of the Python dictionary interface for the JudyL and JudySL API and a subset of the set interface for the Judy1 API, along with some extensions for iterating a subrange of the sorted keys, values and items.
