What exactly is the purpose of the "Catalog Product Rule" and "Catalog Rule Product" indexes?
Which functionalities do they cover?
I am just wondering, because there are often a lot of entries in the backlog of the indexer and we are not using any product rules within Magento that I know of.
Thus I am wondering if I can disable those indexes to make the
indexer_update_all_views cron job a little faster.
Since we have not defined any such rules in our shop: why are there still so many entries to be indexed for the "Catalog Product Rule" index? Are there base rules that Magento always accounts for?
