I wonder the delay for the non-primary,this may make a poor RPO。

#5 Updated by liuzhong chen 10 months ago

there is any advantage for this delay?

@liuzhong chen: indeed -- while it's use-case dependent, it's possible you might want to ensure that the backup site is always X hours behind the primary site just in case you want to provide a window to recover from a destructive change to the primary.
