The Xmin wraparound issue you're experiencing is due to the transaction ID (aka xid) reaching its upper limit value of 4,294,967,295. Once this value is reached, the xid wraps around and stops increasing monotonically. At this point, the xmin column cannot be reliably used as a cursor, which can lead to resyncing data that had already been synced. This can degrade the replication performance and lead to higher credit consumption. Unfortunately, there's no direct way to mitigate this issue without changing the replication method. The recommended solution is to switch to the CDC (Change Data Capture) or cursor-based replication method. This is because both CDC and cursor-based replication methods are more reliable in updating your data and can handle the Xmin wraparound issue more efficiently. If you're unable to switch to CDC or cursor-based replication due to certain limitations, you might want to consider reducing the number of transactions in your database to delay the occurrence of Xmin wraparound. However, this is not a long-term solution and the issue might recur when the transaction count increases.
