Hi Qian, There have been discussions on multiple transaction in zookeeper:
http://www.mail-archive.com/[email protected]/msg08315.html Which I think might help this case. There have been some discussions on this lately but not much progress. You can start a discussion on the list to see what folks feel about multiple transactions. I think if we are to support something like what you mention it should be via multiple transactions wherein a success would mean a success for all the transactions that are part of a multiple transaction.
