How Magento indexing works

Indexing entails how Magento changes data, including product and categories to improve the storefront’s performance. Indexing method is aimed at speeding up the user interface, whereby, it counters the performance problem of Entity Attribute value (EAV); a flexible data storage solution but slow in data reading process. With indexing method, the transformed data updates as the data changes. For efficient performance, Magento stores data into table columns using indexes. View top ecommerce platforms 

However, it’s important to note that even with one product, it’s still worth using the index, although with a slight increase in speed you’re likely to encounter some serious drawbacks. It’s, therefore, necessary explaining some of the Magento indexes and their application for better performance;

Product attributes index

The product attributes index reorganizes the Entity Attribute value (EAV) product structure into a flat structure. It works by collecting the entire attributes that are applicable in the layered navigation for the same purpose. The combination of the two translates into a faster reading of the data. With product attribute index, the data values can be stored separately for different stores since it has different values in different stores.

However, the attributes used in either search layered navigation or category can be included in the index, just implying that only multi-select, select, and price attributes can be included. Also, the product attributes index can efficiently handle complex products such as bundle products and configurable products with multiple child products that a client can choose between. Simply put, this index plays a great role in Magento in allowing category selects (filtering).

Product categories

This indexer creates product and category association which is determined by the type of connection set on the Magento flag group attribute (backend and the ‘is anchor’). The game group attribute gives a list of all the products from its child categories.

Product prices

This type of index in Magento works by pre-calculating the product prices. Given that the product’s price can significantly be affected by several instances/variables, catalog discount rules, for example; likewise, recovering the product prices will call for multiple selections or joins. Moreover, product pricing indexer collects and stores data in individual tables where in turn, it makes the selects much easier. How to the Change Wix Template of Your Website

Catalog search index

This indexer in Magento ensures that one can find the products in a search using different attribute values, even when they are not stored in the little tables. It does so by filling the relevant attribute values about the products in one field which makes it even easier to search them based on keywords.


With those indexes and much more, Magento becomes a pretty powerful and complex system that can allow one to work with various amounts of data and with indexes in place; it guarantees a faster response from the database.
