What is Truncation / Corruption?

Truncation and corruption typically refer to scenarios where data is unexpectedly cut off or altered, compromising its integrity. This can occur due to various reasons, such as sudden power failures, system crashes, or disk errors. Redis mitigates these risks through its persistence mechanisms like RDB snapshots and AOF (Append-Only File) logs.
