Hello,

I was looking at (both) APIs, and it seems to me that there's no way
to perform a consistent attribute read - am I right? You can do a
consistent query, or a conditional put/delete, but for reads there
seems to be an option missing.

In both cases, if you call selectItems, look for the boolean called "consistent", which invokes consistent read.

Yes, but what about a consistent getItem?

I just had another look and it seems that I overlooked the ConsistentRead flag GetAttributes. Drat!

I'll write a bug report so I don't forget to fix that. I'm a semi-vacation week right now, but will see what I can do as this won't take much time to fix.

Here's a patch adding a getItem(String, boolean) method:
