**Issue Evaluation** Category: `type/enhancement` | Status: **Evaluated** **Feasibility:** Feasible **Scope:** `LanguageCode`, `SerializeType` **Compatibility:** No breaking changes — same lookup semantics, just O(1) instead of O(n). Classic JVM optimization. `Enum.values()` defensive copy allocation on every call is a well-known hotspot. The `BY_CODE[]` static array pattern is the standard fix. One consideration: ensure the `BY_CODE` array size matches the maximum code value + 1 (or use a `HashMap` if codes are sparse). For `LanguageCode` and `SerializeType` the code ranges appear dense, so array lookup is appropriate. Low-risk, straightforward change. --- *Automated evaluation by RockteMQ-AI* -- This is an automated message from the Apache Git Service.
