Optimizing a Real‑Time Keyword Matching Service with Aho‑Corasick and Double‑Array Trie

By replacing the naïve double‑loop matcher with a Double‑Array Trie‑based Aho‑Corasick automaton and refactoring the system into a layered name‑and‑data microservice architecture that shards the keyword dictionary and rebuilds the automaton only on version changes, the real‑time keyword‑matching service reduced latency from seconds to milliseconds even at thousands of QPS.
