Answer

When replaying events from a Segment source to a destination, it is important to note that not all destinations support data deduplication. Replay actions may result in duplicate records if the destination does not automatically filter out repeated events. To minimize the risk of duplicates, replay only the specific time windows where data was missing, rather than the entire period. Before initiating a replay, consider deleting, archiving, or removing any older versions of the data in the destination.
