Yes, <br><br>Currently, you can have 1 master & multiple slaves, but not multiple masters sinking over each other because there are marker translators which set extended attributes & so there is a chance of that getting corrupt. <br>

I tried to configure a bidirectional geo-replication between 3<br>
