How reindexing process is works in Magento 2?

Question

If i have 1 lakh product in my store and i have re-index in Magento 2.

If i changed a product price so it is required to re-index in magento 2 to see the updated price.

And if it is required to re-index then Magento will re-index all the product from starting or just re-index the updated one.

Any help is appreciated.

Answer 1

We can perform both type of re-indexing

a) Full reindex, which means rebuilding all the indexing-related database tables.

b)Partial reindex, which means rebuilding the database tables only for the things that changed (like changing a single product attribute or price)
