Hi Dave
Sorry For Late Reply
1] Expected Number Of Document upload at First 8,575,844 each of 2MB
i.e. nearly 16-17 TB.
I am adding these documents as attachment.
For my test purposes I tried to insert 1000 documents of 1.37mb each.my
program took approx. 8 Min to insert these number documents with this
much of data size.
At this rate it will take 5 days to upload 1TB of data, Which is too
much of time kindly know I am missing something.
Thx,
Ajay.

Hi Ajay,
You've asked a pretty general question and not given a lot of details,
so it's hard to give a solid answer.
1. size
There are couches significantly larger than 1TB. The number of docs is
likely a more useful measure. Again there are DBs out there with
hundreds of millions of docs.
2. attachments
CouchDB "does" attachments, and can stream these to/from disk after
retrieving the necessary meta-data from disk. So assuming you are not
disk IO bound your throughput will likely be limited by your HTTP
connection anyway.
3. General:
I'm not familiar with the client libraries for .Net, can anybody else
advise?
If you have some more specific figures and use cases in mind, perhaps
somebody can offer a more useful comparison. Things like numbers & size
of doc, compatibility with JSON, level of updates to docs, relations
between docs, redundancy & replication needs, working set constraints,
frequencies & types of queries you need all play a part.
A+
Dave
