Andrus, I've almost finished the collecting of values from the various BatchQueries. The one that remains is getting the old value for a column from UpdateBatchQuery. I know that these values are available as part of the qualifier when optimistic locking is used, but I don't know if that's the best way to get them.
What do you think of having the old value snapshot stored directly on UpdateBatchQuery and made publically accessible? I'm not sure if this might make dealing with optimistic locking easier or not in the process.
