Older offsets can overwrite newer ones in Kafka if not handled properly.

Kafka consumer reprocessing involves safely replaying events to correct system states.

Kafka's commitSync waits for confirmation, while commitAsync continues immediately.

Kafka consumers can use multiple threads to speed up message processing, but it complicates ordering and offset management.

Kafka's `seek()` lets you replay only specific messages, saving time.

Kafka consumers have three important states: Position, Committed Offset, and Application State.

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

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

Kafka's pause temporarily stops reading messages, while seek changes the reading position.
