Hi,

I don't see the replication type in the metadata replication contract. For
example someone can use MySQL Galera cluster with synchronous replication +
asynchronous replication master-slave for backup to remote site.

MS SQL offers alwaysON availability groups clustering with pair of
synchronous replication plus up to 3 nodes with asynchronous replication.
Also there are some existing different mechanisms like data mirroring
(synchronous or asynchronous) or log shipping.

So my point is that when you say replication, it is not obvious which type
of replication is used.

Thanks
Georgy
