New 1.7 SimpleDB API, batch puts, and replace

[tim_darby]

Hi,

First up, I've almost entirely switched to the refactored SimpleDB API
and I find it has cleaned up my code nicely.

Just thought I'd check in case I've missed something, but it looks to
me like I can't combine use of batchPutAttributes with setting the
'replace=true' flag on the attributes, as its either
batchPutAttributes which takes a list of items, or its
replaceAttributes, which just takes the key and the map of replaced
attributes.

Is this correct, and if so is there any possibility of getting the API
enhanced to include a batchReplaceAttributes?, as I've got some code
which otherwise will be taking a dip in performance with the switch

Thanks

Tim

Now that I'm looking at this, I see what you mean. In simplifying the Item interface to be more precise, I did away with the "per attribute" replace flag. I figured that'd be defined in the API functionality.

I wonder if anyone uses replace on an attr by attr basis? Can batchPutAttributes have an additional replace flag param?

This would set the replace flag on all the attr changes, yes? That'd
be fine by me as for all my use cases I either know I need to replace
for the call generally, or know I don't need to, but can't really know
ahead of time if I can afford the cheaper non-replace on some but not
others.

In short, for me, that'd be great.
