问题
Recently I ran into a problem regarding Re-index in Magento.
My store has around 40,000 products and If I change a status of a single product, changes are not reflected on frontend as it needs reindexing of all Indexes.
Moreoever reindexing takes a hell lot of time (around an hour) and I am thinking of a permanent issue.
What does "Save on Update" mode in Reindex specifies ? Does it help in reindexing while saving the product ?
Whats the difference between manual update and update on save ?
Please help.
Thanks in advance.

Use the "Update On Save" re-indexing mode, it will do re-index on the fly for that single product you have saved.

I assume you mean "Update on Save" when you say save on update, also called as "realtime" mode which triggers the re-indexing of product data every time the product has been saved / updated.
Basically in Magento there are only two modes of re-indexing "Update on Save" (Realtime) and "Manual". Their names speak their mode of behavior quite clearly.
In your case, as you have huge amount of products in your store, do the re-indexing through Magento SHELL commands like the following which in turn saves you a lot of time.
SSH to your store and go to shell folder inside your magento root and re-index one by one or all in one shot
php indexer.php --reindex catalog_product_flat
php indexer.php reindexall

The magento manual (http://docs.magento.com/m2/ce/user_guide/system/index-management-manual.html)
States:
Set Actions to “Reindex Data.”
Its too bad the options are not available! Do you see those options in your admin pages? If not, is there a reason why it might not show up?
I would like to do update on save, but this is not really practical. I imported a large number of products from CSV.
I tried running the re-indexer from the command line, but by shell directory is missing.
magento missing shell directory
Well, it looks like I am fresh out of ideas! Maybe I should just pay Varien to run Magento Enterprise for me. Afterall, re-indexing is a bit complicated, isn't it?
