Hi, I think your recipe will work ;)

My situation is different a bit from Naveed. My database is RDBMS, but i 
want to store uploaded file in a Key/Value storage(NoSQL). How can I 
intervent to store/retrieve process? 
I want to temporarily store uploaded file in memory, than call API to put 
this in-memory file to my Key/Value storage. (and similar when have 
"retrieve" request)

Could you have me figure it out pls? 
Thanks in advance!
