This method can also be used to refresh from storage, retrieving any changes made since the row was last read from storage.

ident_condition

my $cond = $result_source->ident_condition();

my $cond = $result_source->ident_condition('alias');

Produces a condition hash to locate a row based on the primary key(s).
