## Summary - Pre-parses the replacement template once (`ReplacementTemplate`) to avoid re-parsing `$` backreferences on every row - When the replacement has no capture group references, uses `Regex::find()` instead of captures — leverages the fast DFA/hybrid engine and completely avoids the expensive `BoundedBacktracker` - When capture groups are needed, uses `captures_read()` with pre-allocated `CaptureLocations` to avoid per-row `Captures` allocation, and writes results directly into the output buffer ## Test plan - [x] Existing `regexp_replace` unit tests pass - [x] ClickBench regexp sqllogictests pass - [ ] Benchmark with ClickBench Q28 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
