Re: Read Write Performance Graphs

2008-10-02 Thread Patrick Hunt

Thanks for the report Stu. I have created a jira to address this:
https://issues.apache.org/jira/browse/ZOOKEEPER-154

Feel free to create jiras for any documentation issues you might find. 
We are keen on improving the docs now that we have a more structured 
format (we are using apache forrest). Just assign the jira to the 
"documentation" component.


Regards,

Patrick

Here is the missing text:
To show the behavior of the system over time as failures are injected we
ran a ZooKeeper service made up of 7 machines. We ran the same
saturation benchmark as before, but this time we kept the write
percentage at a constant 30\%, which is a conservative ratio of our
expected workloads.

Question regarding the current docs: the "Reliability in the Presence of
Errors" graph on
http://hadoop.apache.org/zookeeper/docs/current/zookeeperOver.html does
not list how many ZooKeeper quorum nodes are in use, or the fraction of
reads/writes.

I'd like to use the graphic in a presentation, but I'm sure someone will
ask these questions.

Thanks tons!
