In general,\nm2-slave should not be used directly by application for\nfailover. The dbproxies handle that transparently to the\napplication. Using it for critical tasks should be avoided\nto prevent a split brain scenario.\n\nIt should only be used for low-hanging tasks, where lag is not\nimportant, such as backups, dumps, statistics, ... not for an\nactive application.\n\nChange-Id: Icff5045fce3a23044d0de55042f91718f59e94f3","distinct":true,"url":"https://api.github.com/repos/wikimedia/puppet/commits/cd3164be8915fa608b57f68e78b5258addfcc5df"}]}
