Modes of editing topic offsets

Within the consumers menu, when selecting a consumer group, there are two options for editing offsets, one in the actions button and the other for each partition. What is the difference between them?

Hello Edward_k,

The actions button is used to edit the topic as a whole. Because the partitions are not correlated or connected, you can only edit to the earliest offset, latest offset, or a specific point in time of the topic offsets. In accordance with your image, it would be the popup on the right. When editing a single partition, you can only change by offset and not edit by time, because editing by time offers no guarantee of when a particular set of messages entered, especially compared to another partition. In your picture, it would be the left popup. These are the differences between these buttons when editing the offset.
