I for got one "within a session" in the previous text ...
... This means that if a client sends a write *within a session*, AND no
other client modifies that information, it will always see the result of
that write in any subsequent read ...

hello,
I believe that if you observe that, you should try to reproduce it
with TRACE logging level and open a JIRA with the case sending the logs.
If I am not wrong, ZooKeeper transactions are guaranteed to be executed in
sequential order in all servers and within the client session. This means

I am trying to update one of our znode data from zkCli. And I am trying to
insert simple json document in one of our znode data.
And whenever I execute the below command from cli, I always get below error

I have a question about the consistency guarantees of zookeeper.
As far as I understand, zookeeper provides eventual consistency guarantees.
Updates are not guaranteed to be seen by read operations following an
update (reads are not necessarily consistent). The reason behind this is
that reads mig
Thanks a lot Diego. Let me see whether I can put that example using the
basic approach or not.
By decorations approach you mean the approach I am doing currently right
like this? -
@zk.ChildrenWatch("/my/example")
def watch_children(children):
print("Children are now: %s" % children)
Hello Techy,
The decorations approach you are doing may not be the best way to handle
your use case. I don't know very much about the python binding but I think
you'll need to do the watch programmatically to achieve the what you are

Can anyone help me with this? I am stuck on this problem..
Or if there any better python client for Zookeeper then please let me know
as well?

Hi,
I'm currently having only one Zookeeper instance (ZK1) and would like to
upgrade to a 3 instace quorum (ZK1, ZK2, ZK3).
I understand that this can be done by rolling restarts, but since ZK1 was in
standalone mode until now, it's missing the myid file.
Do i need to create the myid file for ZK1
