Question: 1 / 400

What does setting unclean.leader.election.enable to false imply?

Better availability for partitions

Higher risk of data inconsistencies

Preference to maintain original leaders for data integrity

Setting unclean.leader.election.enable to false implies a preference to maintain original leaders for data integrity. When this setting is disabled, the Kafka cluster protects against electing a "dirty" leader—one that might not have all the latest data due to broker failures or network partitions. By ensuring that only a fully synchronized replica can become a leader, Kafka aims to maintain consistent data across the cluster. This helps in preserving the integrity of the data by preventing situations where a leader with outdated or incomplete messages is chosen, which could lead to inconsistencies and loss of valuable information in the system.

In contrast, other options either promote availability or imply potential risks associated with data integrity.
