Thanks for the pointers but I am planning to revolve more around AWS ecosystem so that I have less ops burden of managing servers + regionalization becomes easy.

Entire cycle in sub-second. I agree that it depends on many factors but as per the system, we are looking subsecond from ingestion of data from client to availability of data for query.

A -> stream -> datastore (subsecond)

I am also okay to dump the whole architecture and re-architecture. Will do a POC but looking to know, if some one has designed something of this sort.
