Sorry for the spam everyone... If I were to start a tap with the start date of April 1st, and then later want to change that start date to get data from before April 1st (change to March 1st or something) will it reset the progress or just fill the data that hasn't been collected yet?

Unless the tap can be configured with an end date or some other window, it would incrementally process everything from March 1st onward.

Ah, thank you... this is what I expected. I am using tap-klaviyo and I don't believe it has an end_date value for the config. Thank you!
