Attribute Set:
Attribute set is a list of certain relevant attributes to each product types. It is used each time when a new product is created. Magento 2 provides a Default attribute set. Users also have the option to create their own custom attribute sets in Magento 2.
In this article, I will explain how you can create custom attribute sets in Magento 2. And also

Why via upgradeData:
If we need to insert any table related data (like attributes/attributeset/attibutegroup) after the module installation, we go for upgradeData.
/*
* We declare the namespace of our module to avoid conflicts around multiple modules and introduce more flexibility
*/
namespace Apptha\Blog\Setup;
/*
*The below are the namespaces and and classes to be included in order to create new custom attribute set programmatically
*/
use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\UpgradeDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Catalog\Setup\CategorySetupFactory;
use Magento\Eav\Model\Entity\Attribute\SetFactory as AttributeSetFactory;
/*
* UpgradeDataInterface brings the ‘upgrade’ method which must be implemented
*/
class UpgradeData implements UpgradeDataInterface
{
private $eavSetupFactory;
private $attributeSetFactory;
private $attributeSet;
private $categorySetupFactory;
public function __construct(EavSetupFactory $eavSetupFactory, AttributeSetFactory $attributeSetFactory, CategorySetupFactory $categorySetupFactory )
{
$this->eavSetupFactory = $eavSetupFactory;
$this->attributeSetFactory = $attributeSetFactory;
$this->categorySetupFactory = $categorySetupFactory;
}
public function upgrade(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
$categorySetup = $this->categorySetupFactory->create(['setup' => $setup]);
/**
*checking the current version of the module
*this function is implemented from ModuleContextInterface
*/
if(version_compare($context->getVersion(), '1.1', '<')) {
$attributeSet = $this->attributeSetFactory->create();
$entityTypeId = $categorySetup->getEntityTypeId(\Magento\Catalog\Model\Product::ENTITY);
$attributeSetId = $categorySetup->getDefaultAttributeSetId($entityTypeId);
$data = [
'attribute_set_name' => 'Apptha_Custom_Attribute_Set', // define custom attribute set name here
'entity_type_id' => $entityTypeId,
'sort_order' => 200,
];
$attributeSet->setData($data);
$attributeSet->validate();
$attributeSet->save();
$attributeSet->initFromSkeleton($attributeSetId);
$attributeSet->save();
}
}
} ?>
Add these code in upgradeData.php under app/code/namespace/module/setup and update the version in module.xml under app/code/namespace/module/etc as below
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="Namespace_ModuleName" setup_version="1.1" />
</config>
Upgrade the module setup using upgrade command via CLI and see the custom attribute set is created.
The command to upgrade the module via CLI is given below.
php bin/magento setup:upgrade
The save function will be deprecated for entities as far as I know
