This section discusses known problems or issues when using replication with NDB Cluster. A loss of connection can occur either between the source cluster SQL node and the replica cluster SQL node, or between the source SQL node and the data nodes ...
https://dev.mysql.com/doc/refman/8.4/en/mysql-cluster-replication-multi-source.html
Not all MySQL servers taking part in multi-source replication must act as both source and replica, and a given NDB Cluster might use different SQL nodes for different replication channels. It is possible to use NDB Cluster for bidirectional ...
