Complex sentence: Judy arrays are both speed-and memory-efficient, with no tuning or configuration required and therefore they can replace common data structures (skiplists, linked lists, binary, ternary, b-trees, hashing) and work better with very large data sets.
Split into simpler sentences: Judy arrays are both speed-and memory-efficient, with no tuning or configuration required. With better usage of memory and speed, Judy can replace common data structures (skiplists, linked lists, binary, ternary, b-trees, hashing) and it improves with very large data sets.
