Galera Mysql Cluster XA transactions alternative

Question

On Galera Mysql Cluster (either Percona or MariaDB) limitation refers that XA transactions are not supported, cause of cluster nature, which is perfectly understand. My question: (i am not a developer so please show some mercy on me) is there any mechanism that replies an OK if the statement has been committed to majority of nodes - something like MongoDB write concern?

Answer 1

Galera replication is synchronous and when a write query gets back to you, the data is on every node in the cluster. If for any reason a node cannot apply the transaction, it will kill itself to maintain the integrity of data throughout the cluster.
