From 7dea3605a038f4502c042aeecaea89cb5280fdf9 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 19 Mar 2026 17:41:31 +0000 Subject: [PATCH] =?UTF-8?q?=E2=9A=A1=20Bolt:=20Optimize=20case-insensitive?= =?UTF-8?q?=20routing=20comparisons?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaced allocation-heavy strings.ToLower() == strings.ToLower() checks with zero-allocation strings.EqualFold() in pkg/routing/route.go. What: Replace `strings.ToLower(a) == strings.ToLower(b)` with `strings.EqualFold(a, b)` in `ResolveRoute` bindings checks. Why: `ResolveRoute` is an extremely hot path evaluated for every single incoming message across the system. Calling `strings.ToLower()` allocates new strings on the heap and creates unnecessary GC pressure for case-insensitive checks. Impact: Reduces memory allocations during feature routing bounds checking from O(N) to O(1) by performing zero-allocation case-insensitive evaluations. Measurement: Compare memory allocations and CPU profiling in `ResolveRoute` or run benchmark tests checking routing rules.
