## 9. Error Handling

### 9.1 Cache Consistency
```java
public class CacheConsistencyManager {
    public void handleInconsistency(String directoryPath, String fileName) {

        if (total == 0) return 0.0;
        return (double) operationErrors.get() / total;

### 9.1 RDMA Error Recovery
```java

                resource.setAttributes(0x20);

### バックグラウンドタスクと `yield` を伴う依存関係、技術詳細 { #background-tasks-and-dependencies-with-yield-technical-details }

FastAPI 0.106.0 より前では、`yield` の後で例外を送出することはできませんでした。`yield` を持つ依存関係の終了コードはレスポンス送信「後」に実行されるため、[例外ハンドラ](../tutorial/handling-errors.md#install-custom-exception-handlers)はすでに実行済みでした。

これは主に、依存関係が "yield" した同じオブジェクトをバックグラウンドタスク内で利用できるようにするための設計でした。終了コードはバックグラウンドタスク完了後に実行されるからです。
