What is the difference between --to-latest and --to-current offset values

Below is the comment in the Apache Kafka repository.

  --to-latest : Reset offsets to latest offset.
  --to-current : Resets offsets to current offset.

What is difference between two option? Aren't they both the same thing?

The latest option ignores committed offsets and seeks the group to the highest offset for all partitions.

The current option resets to the committed offsets, which I believe would be a no-op for any non-active consumer group.

For a group with zero lag, both options will do the same thing.

Source: https://github.com/apache/kafka/blob/3.0/core/src/main/scala/kafka/admin/ConsumerGroupCommand.scala

The current option is explained in KIP-122

When we want to only print out and/or backup the current offset by partition.
