Is there any SQL Database that will use UDP replication?

I have to find a database that will ensure the UDP replication intercontinental. 1. Do you know if there is any SQL database that will support UDP replication? 2. If not, can I use MySQL replication (TCP/IP protocol) intercontinental (from China to Switzerland)? Will this work fine? Won't be any meltdowns? How can I prevent them? 3. The master will be in China and the slave in Switzerland. If the slave will be down for a long period of time, and the logs used to update the replications will be too big or not enough, how can I handle the replication? What is the solution? Thank you and kind regards, Andreea
