Hi Folks,
As I mentioned in an early post , I am working on a personal project to extract Zab (zab <https://github.com/aoriani/zab>) from ZooKeeper for my MS project. I am doing that by bring one class from Zookeeper to my code at time. I am not planning to have clients , so the only proposer are the servers in the quorum. Now that I have finish bringing the leader election (almost , still need to bring NEWLEADER proposal) , I am starting with I think is the hard part: Leader, Leaner e Processor classes. They are harder because I need to change code dealing with Zookeeper requests to work in a abcast/adeliver fashion. Well, stopping the chitchatting, my question is : the class Request has the fields cxn, sessionId,cxid and TnxHeader has also clientId. I did a grep on the code and little operation is done over those fields. Most of the time they are copied from a data structure to another. My guess is that they are used by the quorum members to identify if committed proposal belongs to one of its clients. Since my code is not going to deal with clients, can I remove those fields? Or do they play some role in the atomic broadcast protocol that I haven`t realized yet ? Thanks, André
