Understanding the Differences between Magento 2 Cache Clean and Cache Flush

Magento 2 for Ecommerce has turned out to be a robust platform as it offers a solid set of features and functionalities for building and managing Ecommerce stores. If you are an Ecommerce business owner, who is planning to opt for Magento development services, you should first get a good understanding of the intricacies of its caching system. Knowing these details beforehand will help you to ensure that you hire a Magento expert that possesses expertise in this domain.

Efficient cache management tends to play a key role in making sure that your Ecommerce store runs efficiently and smoothly and thereby offering a smooth user experience. Here in this detailed guide, we are going to discuss the key distinctions existing in between “Cache Flush” and “Cache Clean” in Magento, which are two most important operations for maintaining the performance of your store. So, let’s get started:

What is Referred to as Caching in Magento 2?

Caching is known to be a useful technique that is typically employed for frequently storing accessed data especially in a temporary storage area. It facilitates swifter access to this data. Not only that, but it helps to effectively reduce the load on the server. There are many different caching mechanisms that are used by Magento 2 to boost performance. It includes the following

• Configuration Cache: Stores the configuration files.
• Block HTML Output Cache: Caches HTML output of blocks.
• Layout Cache: Holds compiled page layouts.
• Reflection Data Cache: Holds data from the Magento Object Manager.
• Collection Data Cache: Stores database queries.
• EAV or Entity-Attribute-Value Cache: Caches attribute and value data.

In case you are planning to go for Magento web development services, it becomes crucial to get an understanding on how to effectively manage these caches. Let’s find out how:

Cache Clean vs. Cache Flush: Understanding the Distinctions

Both “Cache Clean” and “Cache Flush” are operations that help manage the Magento 2 cache, but they serve different purposes and have different impacts on your Magento store.

Cache Clean

When you perform a Cache Clean operation in Magento 2, you are selectively removing only the outdated or invalid cache entries. This means that Magento will only delete cache data that has been modified or is no longer needed. Cache Clean is generally safe to use and does not require reindexing the store.

Cache Clean: Use Cases

Development and Testing

During the development phase, especially when you hire Magento developers to customize your store, frequent changes are made to the code and configurations. Using Cache Clean ensures that only the modified data is refreshed, minimizing the performance impact.

Routine Maintenance

Regularly cleaning the cache can help maintain store performance without the need for a full cache flush.

Minor Configuration Changes

When making small changes to the store’s configuration or design, Cache Clean is ideal as it does not disrupt the entire cache system.

Cache Flush

Cache Flush, on the other hand, removes all the entries from the cache storage, regardless of their validity. This means that every single piece of cached data is deleted, forcing Magento to regenerate the cache from scratch. This operation can be more disruptive than Cache Clean and might require a full reindexing.

Cache Flush: Use Cases

Major Updates

When performing significant updates to the Magento core, themes, or extensions, a Cache Flush ensures that all outdated data is removed, and the latest changes are fully reflected.

Performance Issues

In cases where the store is experiencing performance problems, a Cache Flush can help by clearing out any potentially problematic cache data.

Debugging and Troubleshooting

If you encounter persistent issues that are not resolved by Cache Clean, a full Cache Flush can help eliminate corrupted or stale cache entries.

Why is it Crucial to Perform Cache Warm-Up?

After performing a Cache Flush, it is a good practice to warm up the cache. This involves pre-loading the cache with frequently accessed data to reduce the initial load times. Various extensions and scripts are available to automate the cache warm-up process.

Here is an example of a simple cache warm-up script:

#!/bin/bash

# List of URLs to warm up

urls=(

“https://yourstore.com/”

“https://yourstore.com/category”

“https://yourstore.com/product”

)

# Loop through URLs and fetch them to warm up the cache

for url in “${urls[@]}”; do

curl -s -o /dev/null $url

done
