Magento - disable indexer for specific store

Question

I'm using 5 stores only for orders (no frontend, only backend).

Is there a way to disable indexer process (especially catalog_product_flat and catalog_search) for specific store id?

Answer 1

you can't disable it in configuration. it's easy to do for the flat index, you have to update a loop where it creates

\Mage_Catalog_Model_Product_Indexer_Flat::_processEvent

The next step is:

\Mage_Catalog_Model_Product_Flat_Indexer

The next step is:

\Mage_Catalog_Model_Resource_Product_Flat_Indexer

Now one of the main functions (this function calls rebuild function and fill data into the table):

\Mage_Catalog_Model_Resource_Product_Flat_Indexer::reindexAll

And your final call:

\Mage_Catalog_Model_Resource_Product_Flat_Indexer::rebuild

There is a loop in the function:

public function rebuild($store = null)
{
    if ($store === null) {
        foreach (Mage::app()->getStores() as $store) {
            $this->rebuild($store->getId());
        }
        return $this;
    }

if you update this loop, you can skip the desired store from flat indexer. Location of the function is: app/code/core/Mage/Catalog/Model/Resource/Product/Flat/Indexer.php:121

And very similar logic for a FullText search index: \Mage_CatalogSearch_Model_Resource_Fulltext::rebuildIndex
