Hi, Yisheng extended his internship for another three month. Here is the current status of the project:
- Released 0.1.0. This is an alpha quality release, and it supports all the basic functionalities including snapshot, reconfiguration, and SSL. http://search.maven.org/#artifactdetails|com.github.zk1931|jzab|0.1.0|jar - Performance looks reasonable. It can do about 22k requests per second on a 3-node cluster even though our log implementation is fairly naive. https://github.com/zk1931/jzab/wiki Yisheng started working on a Curator-like library on top of jzab that can support data structures like map and queue. Let me know if you have any other interesting project ideas.
