Hi,

I use boost log in an embedded system where flushing log message to
flash storage need be controlled. I could not find how to change log
auto flush rate, is it the only way to disable auto flush
boost::log::keywords::auto_flush = false? I think there must be a way
to change a desired log flush rate value without disabling auto flush,
appreciate any tips.

Thank you.
