In this section, you will learn to develop high-level distributed system constructs and data structures using ZooKeeper. As mentioned earlier, most of these constructs and functions are of utmost importance in building scalable distributed architectures, but they are fairly complicated to implement from scratch. Developers can often get bogged down while implementing these and integrating them with their application logic. In this section, you will learn how to develop algorithms to build some of these high-level functions using ZooKeeper's data model and primitives and see how ZooKeeper makes it simple, scalable, and error free, with much less code.
