Using the Dropbox Datastore API in Python

This could be a fantastic opportunity for startups to scale more quickly without most of the per-user costs. If the user brings his own storage, I don't have to pay Google/Amazon/etc. to put the user's data in my app's datastore. Since Dropbox has utility to the user beyond just my app, I don't have to convince the user to start a subscription with me to cover his share of my costs; he already has a Dropbox account. As long as Dropbox comes with 2GB free storage, he doesn't even have to be a paying customer.

I love the sound of this but remain cautiously optimistic. One thing that immediately comes to mind: How do you prevent the user from breaking their own user experience by deleting folder X or moving file Z?<p>My thought would be to create a locked folder accessible only by APPX and then if the user decides they don&#x27;t want to use the service any more and revokes permission to APPX the folder gets deleted.

I wonder if Guido is behind this. He wrote the Datastore API for AppEngine, and transferred to Dropbox last year.

Any benchmarks? Number insert &#x2F; second? Num of query &#x2F; second?<p>What are the limit on number of records, number of field (column?) in a table? How many tables can one have?<p>How often is the commit? Is it commit to local&#x2F;fs or to the cloud (under what condition)?<p>How does the datastore sync from different devices works?

I wonder whether it&#x27;s intentional that the tutorial isn&#x27;t &quot;copy-pastable&quot;.<p>Specifically, it does not spell out any of the imports, and uses very large except clauses.

If I knew Python more I would write a Sublime Text plugin that syncs my settings over Dropbox.
