| Anjo,
No, I haven't looked at CouchDB until now (on Wikipedia).
The limits you mentioned on SimpleDB are interesting:
If I'm reading the 250M attribute name-value pair limit correctly, that means a domain (table) with 10 attributes (columns) could only hold 25M rows of data provided the total for the domain was less than 10 GB.
While this sounds small, I'm speculating that if a SimpleDB customer was close to that limit Amazon could increase the limit on a case-by-case basis.
Cheers, Joe

I've been backing up some historical data that doesn't change to SimpleDB. It doesn't seem like the pricing is bad at all - I've put more than a million rows into a SimpleDB domain without any problems. Each SimpleDB write is done in a separate thread since it takes about one third of a second to complete the write (S3 writes typically take between 1-5 seconds to drop an object in a bucket).
But it got some limits like the number of fields*rows < 200 million or sth... you ever looked at couchdb or some other column storages or map/reduce based things? Cheers, Anjo
