not guaranteed whether the statement will be executed on a slave or
not. This is how often the internal
that a slave shall be used. Please, see also the user space function

Number of statements the built-in query analyzer recommends sending
use_master_guess
to a master because they contain no SQL hint to force use of a certain

not. This is how often the internal
that a master shall be used. Please, see also the user space function
mysqlnd_ms_query_is_select.
