Just a thought, but if there was a way to annotate tables in Persistent as append only, that would open to the door to some cool, application-side caching in persistent.

Note that simply omitting "Update" from the table definition is insufficient since the row could still be deleted.

Michael et al., what do you think?

I'm not sure it's a good idea at the table definition level: I could definitely see a case where you want your webapp itself to only append, but you would want to write a utility on the side that could modify as well. I think the best approach would be to provide a wrapper around a standard Persistent connection that limits the operations to only appending, and simultaneously adds the caching. Does this make sense? Michael
