Hi Kamal, There's no such limitation, so most likely this is related to the implementation of your TCP source connector. Do keep in mind that just by the nature of TCP, I doubt that you will have any guarantees when it comes to this source. E.g. if you roll back to a savepoint of one day ago, how will you be able to retrieve the data from your TCP source that's exactly the same as it would be a day ago.
