Classifying failures and using controlled retries in Kafka prevents outages.

Kafka consumers resume processing from the last committed offset after a crash.

Kafka uses retries and Dead Letter Queues to manage message processing failures.

You can replay Kafka events safely by separating live and replay processes.

Kafka lag recovery time is how fast consumers can process backlogged messages.

Kafka Partition Reassignment moves replicas between brokers while keeping data safe.

Kafka allows safe message reprocessing by resetting consumer positions without altering data.

Kafka uses retry topics and delayed retries to manage message failures efficiently.

Kafka uses different strategies to assign partitions to consumers in a group efficiently.
