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!
