Force reads on Master in Master-Slave configuration
I want to use MaxScale to scale the reads throughput.
But I also want to only use 2 instances: 1 Master and 1 Slave.
When using the read-write-split router in this configuration, only the slave receives the reads. Is there a way to also allow reads on the master?
I've found in the documentation: https://mariadb.com/kb/en/mariadb-maxscale-24-readwritesplit/#master_accept_reads "By default, no reads are sent to the master as long as there is a valid slave server available. If no slaves are available, reads are sent to the master regardless of the value of master_accept_reads."
Ok, so "by default" means that there is a way to force reads on the master?

To allow reads on the master, add master_accept_reads=true in the service section.
