How to perform bulk operations in SQL Agent?

// .limit() paginates Array by 50 items
some_array.limit(50, function(items, next) {

    var sql = DB();
    var builder = [];

    // Creates raw SQL queries
    for (var i = 0, length = items.length; i < length; i++) {
        var item = items[i];
        builder.push('INSERT INTO tbl_products (id, name, price) VALUES({0},{1},{2})'.format(sql.escape(item.id), sql.escape(item.name), sql.escape(item.price)));
    }
    
    // Runs one big query
    sql.query(builder.join('\n'));
    sql.exec(function(err) {
        err && console.error(err);
        
        // Process next 50 pieces
        next();
    });

}, () => console.log('DONE'));
