Problem Statement

Investigated suspected memory leak in metabase.util.malli.registry/cache atom. Initial reports suggested unbounded memory growth during test runs.

Root Cause Analysis

The real issue wasn't a memory leak, but fundamentally broken caching for function schemas. With the original schema-cache-key implementation, schemas containing function objects generated unstable cache keys because:

(fn [x] ...) creates new function objects each time Function objects have different identity even with identical code This caused cache misses for functionally identical schemas
