The Silent Killer: Consensus Bugs

Consensus bugs are incredibly difficult to diagnose because they often manifest as subtle data inconsistencies. These bugs can lead to divergent cluster states and ultimately, application failure. Understanding and mitigating these risks is crucial for maintaining a reliable infrastructure.
