Subject [jira] [Commented] (DIRKRB-173) A Zookeeper based high reliable & performance identity backend
Date Tue, 17 Mar 2015 02:06:38 GMT


Kai Zheng commented on DIRKRB-173:

Hi Kiran,

Glad to have this discussion. We don't have specific usecase, but I thought the background
would be Hadoop, and cloud, where high reliability, high performance and high scalability
are highly desirable for any potential component to be hooked into. Zookeeper would be a good
choice in this aspect. It's demonstrated in wide spread usages in big data and cloud environments
as the coordination brain, critical configuration storage and etc. Yes it's also lightweight
and can be embedded. It's also a tree, each znode being of key-value pairs. Looks like we
share the same considerations in this, I don't like RDBMS here. Lin's working on the Json
based one for its easy lightweight and inspecting; I'm working on this for any serious consideration.
I guess we should also get the LDAP one out, but with the Json file based one and ZK based
one out, we may be sure to have more ideas how to implement it.
