In the documentation for the Galera Cluster, galeracluster.com/documentation-webpages/performance.html#setting-parallel-slave-threads, it’s stated that you need to set the following two variables:
innodb_autoinc_lock_mode = 2
innodb_locks_unsafe_for_binlog = 1
Now it turns out that the second variable is deprecated.
Should one set innodb_locks_unsafe_for_binlog = 0? In a master-slave configuration, will it then have any effect to set wsrep_slave_threads > 1?
