NitroPack allows you to set automatic cache purge for specific attributes. Here’s everything you need to know and how to enable it.

Purging the NitroPack cache in Magento clears stored data, ensuring that users see the most recent version of a product or page. This process is crucial for maintaining an updated, efficient online store and ensuring your visitors are exposed to the latest information about your product offerings.

Cache should be purged whenever product attributes are updated, especially for attributes critical to the purchasing process, such as available units and colors. This practice ensures immediate reflection of changes, offering accurate information to customers and maintaining optimal site performance.

Purging cache, especially for stores with thousands of products, can be resource-intensive and potentially strain performance. NitroPack empowers Magento users to selectively determine which attribute changes trigger a cache purge, offering precise control and optimizing performance without unnecessary cache clearing.

In Magento's Admin interface, under Stores >> Product, administrators can configure cache purge settings.

For each attribute, there’s an option “Purge Nitro Cache” in the “Values Required” section, with a 'Yes' or 'No' dropdown menu. The default value for this setting is 'Yes.'

When updating existing attributes, setting “Purge Nitro Cache” to 'Yes' prompts NitroPack to automatically clear the cache, making changes immediately visible on the storefront.

To adjust this setting, click on the attribute and in the 'Purge Nitro Cache' section, choose whether changes in this attribute should trigger an automatic cache purge.

The “Purge Nitro Cache” option is also available for new product attributes, ensuring consistent cache management across all product features.

In the NitroPack dashboard (System >> NitroPack >> Settings), you will see a widget in the bottom-right corner that shows attributes configured for cache purges upon changes.

This widget helps administrators effectively track and manage their cache preferences. Additionally, a “Manage All Attributes” quick access button provides a shortcut to the Products section and its attributes.
