Regular Expression Indexing for Log Analysis
Summary: REI: n-gram-based indexing plus compact storage for logs to accelerate regex queries—up to 14× faster with ~2.1% space overhead. Demonstrates inverted-index variants can be suboptimal for regex-heavy log workloads; REI is modular and plugs into existing regex engines. (summarized by gpt-5-mini on Feb 11 2026)
