i need to override the Mage_Index module to reindex data in a different database. I can't find where can i override the current connection. I need to execute it via shell through "php shell/indexer -reindexall". Anyone could help me?

EDIT (info from comments):

It is needed to get an import of >900000 Products done, where the reindex kills the Shop.


You can create your own local.xml in some folder in app/etc/connections:

<?xml version="1.0"?>

In your code you need to run:

$config = new Mage_Core_Model_Config('connections/local.xml');


Starting magento or running magento scripts you can tell where your local.xml is located.

Mage::app('default', 'store', '/path/to/test/etc');
  • this will not work, if he also wants to use the index tables on the other database. – Flyingmana Jan 28 '14 at 20:36
  • I did not get your point. Could you please explain? – oleksii.svarychevskyi Jan 28 '14 at 21:18
  • Usecase 1: let the index tables create on another database. (solved by your setting) Usecase 2: use this index tables from a different database, when ppl request your side. But still have the normal db as mail, so if someone puts something into cart, its on the main, not the extra database. – Flyingmana Jan 29 '14 at 8:32
  • We don't know what is his goal. If he wants to have several databases for one instance of magento, maybe it would be better to make mysql replication. – oleksii.svarychevskyi Jan 29 '14 at 8:39
  • I need it because i have to import all products and reindex them in another db and than i will do the mysql replication – giovanni Jan 29 '14 at 9:02
