I am running a few smoke tests on branch-3.6, I have also cleaned up JIRA
There is only this task about updating the CI reference in pom.xml

Hi ZooKeepers,
I am checking the new CI system and I noticed this error for branch-3.5 on
the C client build, the error does not occur on branch-3.6 and on master
TestClient.o `test -f 'tests/TestClient.cc' || echo

How is it that participant A would have a later zxid than the leader?
In particular, it seems to me that it should be impossible to have these
two facts be true:
1) a transaction has been committed with zxid = z_0. This implies that a
quorum of the cluster has accepted this transaction and it has
Hello!
We were investigating an issue with consistent reads in ZK which made us
question our assumptions.
We believe that ZK offers sequential consistency such that if a client
creates a node with zxid 0x11122a, it should be able to see (read) all
data changes at least up to that zxid.
Could
I think that the answer depends a bit on what you mean by "client". If you
mean client connection (as in the result of opening a connection to a
Zookeeper cluster), then you should see things in order so that reads
following a successful and acknowledged commit should see only states at or
after th
Can you describe your evidence in more detail as you understand it?

You may have a misunderstanding on what sequential consistency guarantees. For
your example:
Suppose that you have following operations:
create /mypath v0 (0x11000

@李珣The situation you describe may have conceptual deviations about how the
consensus protocol works:---> Since the data of the follower when the follower
uses the DIFF method to synchronize with the leader is still in the memory, it
has not had time to persist1. The write path is: write transact
