+=head1 BULK API
+
+The experimental L<DBD::Sybase> Bulk API support is used for
+L<populate|DBIx::Class::ResultSet/populate> in B<void> context, in a transaction
+on a separate connection.
+
+To use this feature effectively, use a large number of rows for each
+L<populate|DBIx::Class::ResultSet/populate> call, eg.:
+
+ while (my $rows = $data_source->get_100_rows()) {
+ $rs->populate($rows);
+ }
+
+B<NOTE:> the L<add_columns|DBIx::Class::ResultSource/add_columns>
+calls in your C<Result> classes B<must> list columns in database order for this
+to work. Also, you may have to unset the C<LANG> environment variable before
+loading your app, if it doesn't match the character set of your database.
+
+When inserting IMAGE columns using this method, you'll need to use
+L</connect_call_blob_setup> as well.
