We recently migrated to snowplow real time stack. We have moved to Kafka realtime pipeline. The migration went very well. Expect one issue in one of our custom tracking.
So in this custom tracking we have integrated pixel tracker to track email opens. We have observed that the open rate of emails have surged by about 1.5X. The count from other trackers of same tracking is matched to the batch number.
One notable analysis shows that the surge of open rate has no increase in unique user, but shows an increase in open/user.
We are not able to figure out what could be the reason for this. Is the open tracking is duplicated in realtime stack or there was a drops in batch tracking which is fixed now.
Has anyone else faced the similar issue ?
