Greetings,
We (a development team at Canonical) are stumbling into a situation
here which I'd be curious to understand what is the general practice,
since I'm sure this is somewhat of a common issue.
It's quite easy to describe it: say there's a parent node A somewhere
in the tree. That node
Hi Gustavo,
Usually the paradigm I like to suggest is to have something like
/A/init
Every client watches for the existence of this node and this node is only
created after /A has been initialized with the creation of /A/C or other
stuff.
Would that work for you?
Thanks

Hi all,
We're using Zookeeper for Leader Election and system monitoring. We're
also using it for synchronizing our cluster wide jobs with barriers. We're
running into an issue where we now have a single job, but each node can fire
the job independently of others with different criteria in the
Hi Todd,
Just to be clear, are you looking at solving UC1 and UC2 via zookeeper? Or is
this a broader question for scheduling on cassandra nodes? For the latter this
probably isnt the right mailing list.
Thanks

Hi all,
For my $0.02, I really think it would be nice if ZK supported
lightweight transactions. By that, I simply mean that a batch of
create/update/delete requests could be submitted in a single request,
and be processed atomically (if any of the requests would fail, none
are applied).
I know
These are pretty easy to solve with ZK. Ephemerality, exclusive create,
atomic update and file versions allow you to implement most of the semantics
you need.
I don't know of any recipes available for this, but they would be worthy
additions to ZK.
