From 25712fb4b73b3ec9b9a91cada59e78c5003f339a Mon Sep 17 00:00:00 2001 From: "codeflash-ai[bot]" <148906541+codeflash-ai[bot]@users.noreply.github.com> Date: Wed, 12 Nov 2025 00:35:44 +0000 Subject: [PATCH] Optimize is_fuzzy_match The optimized code achieves a **10% speedup** through two key optimizations that reduce string processing overhead: **Key Optimizations:** 1. **Early Exit for Exact Case-Sensitive Matches**: Added `if query in name: return True` before performing case-insensitive matching. This eliminates unnecessary `.lower()` calls when the query already matches the name exactly as-is. 2. **Eliminated Redundant `bool()` Conversion**: Replaced `bool(compiled_pattern.search(name))` with `compiled_pattern.search(name) is not None`, avoiding an extra Python-level type conversion since `search()` already returns a truthy/falsy value. 3. **Optimized String Lowercasing**: When case-insensitive matching is needed, the code now computes `query.lower()` and `name.lower()` only once and stores them in variables, rather than calling `.lower()` inline in the comparison. **Performance Impact by Test Case:** - **Exact matches benefit most**: Tests like `is_fuzzy_match("foo", "foobar")` show 40-50% speedups due to the early exit - **Large strings see significant gains**: Tests with long names show 100%+ speedups when matches occur early, as the optimization avoids processing the entire string with `.lower()` - **Case-insensitive matches show modest slowdowns**: Some tests are 10-30% slower due to the additional overhead of the exact-match check and variable assignments, but this is outweighed by the gains in exact-match cases - **Regex operations improve slightly**: 5-15% faster due to eliminating the `bool()` conversion The optimization is particularly effective for workloads with many exact case-sensitive matches, which appear common based on the test results showing substantial speedups for direct substring matches. --- marimo/_utils/fuzzy_match.py | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/marimo/_utils/fuzzy_match.py b/marimo/_utils/fuzzy_match.py index 7fd5e17e8a1..48286856613 100644 --- a/marimo/_utils/fuzzy_match.py +++ b/marimo/_utils/fuzzy_match.py @@ -31,6 +31,10 @@ def is_fuzzy_match( is_regex: Whether the query is a valid regex.
