There is a very high possibility that your application will run in multiple
JVMs, so you should avoid synchronizing between threads.

I thought of task queue, but the blocking issue there is, we wont get

Code-wise, there is no change that I am aware of.
Conceptually, there are differences - such as potential delays between
a write in one transaction and a subsequent read without using a
transaction to see the newly-updated data.

The Java gdata works great as an api accessing the spreadsheet. If you only

You can expose your own links instead (like /download/{clientid}/{fileid}).
Check if the user is logged in as appropriate and then serve the blob:
