Apache ZooKeeper and The Art of Building Distributed Systems

Event Type: Online
Date: 9/17/2014
Start Time: 1:00 PM
End Time: 2:00 PM
Description:
 Implementing distributed systems can be hard. Servers crash, become slow, and get partitioned away. These are all events that can happen in a real setting and your distributed system needs to be ready to deal with them.

Apache ZooKeeper has been developed to deal with such problems. It is a replicated in-memory system that stores small files called znodes in a hierarchical manner. The ordering guarantees operations over znodes and the notification scheme it provides enables the implementation of a number of commonly used recipes, like master election, group membership, locks, barriers, etc. Without a component like ZooKeeper, implementing such recipes from scratch can be a significant burden because they require sophisticated algorithms with many corner cases that are easy to overlook. ZooKeeper, however, does not make the promise of completely hiding all the problems of a distributed system, but instead to simplify the task.

In this webcast we'll cover:

*Some basic concepts of ZooKeeper
*Design choices, and caveats
*Examples of recipes one can implement with the ZooKeeper API
*Elaborate on the potential problems with na´ve recipes
*Discuss ways around such problems.
