WebMar 6, 2024 · In computer science, a radix tree (also radix trie or compact prefix tree or compressed trie) is a data structure that represents a space-optimized trie (prefix tree) in which each node that is the only child is merged with its parent. Adding an entry to a stream is O(1).Accessing any single entry is O(n), where n is the length of the ID.Since stream IDs are typically short and of a fixed length, this effectively reduces to a constant time lookup.For details on why, note that streams are implemented as radix trees.

WebRedis Streams is an implementation of the immutable log that uses radix trees as the underlying data structure.
