I may be missing something obvious here, but if I use the in tag to iterate over a list in several batches, how can I easily work out what *all* the batches are.

Get the _.len(ObjectValues(...)) and divide by your batch size.

-Michel As I understand it, the last batch can be longer than the batch size, but this solution won't cope with that.

No batch will be bigger than the batch size. If anything, the last batch will be smaller, but it will be the size of the remainder of dividing the total result set length by the batch size.

Of course, this is only if you have 'orphan=0'. Otherwise the math is slightly more complex. There are gobs and gobs of batch processing variables. They are all documented in the DTML Guide. -Michel
