Hi all: I'm a fresh man to Zookeeper. These days, I'm studying on the source code of the C client for Zookeeper, and here are some questions, maybe any one can give me some help.
1. I found in the source of API "zookeeper_interest" that it used a "pipe" to connect with the fd which connects to the Zookeeper server, and used "poll()" to supervise the reading and writing events. I'm not familiar with this usage of combining of pipe and poll. Is there any special advantages in it? 2. I want to conduct a deeply study on both the client and server side of Zookeeper. Could any one provide me the docs of design for Zookeeper? 3. What is JIRA? :-p Thanks for any kinds of help! -- With Regards! Ye, Qian Made in Zhejiang University
