MaxScale's Binlog Router (binlogrouter) allows MaxScale to act as a binlog server. The router can help mitigate the effect of primary failures in MariaDB ReplicationMariaDB Replication deployments. If the primary fails, then the replicas can simply continue replicating existing data from MaxScale. This can also reduce the bandwidth requirements of the primary server in an environment that has a lot of replica servers, since each replica server does not have to download every individual transaction from the primary server. Instead, the primary server only sends a single copy of each transaction to MaxScale, and each replica server replicates the transaction from MaxScale.
