All Implemented Interfaces:

java.io.Serializable

public class LogTruncationException
extends OffsetOutOfRangeException

In the even of unclean leader election, the log will be truncated, previously committed data will be lost, and new data will be written over these offsets. When this happens, the consumer will detect the truncation and raise this exception (if no automatic reset policy has been defined) with the first offset to diverge from what the consumer read.
