There are no ZooKeeper APIs that will allow you to atomically check the value of a node and
change another node based on that value. You’d need to write a recipe for that. i.e. get
a lock (InterProcessMutex), get the value, change another value, release the lock.

Hello,

I would like to know if there is a way to get the value of a node, update it and save it,
all in the same transaction. I have been looking for a way to do that but no luck.
Any idea?

Thanks
Ben
