This post is the second in the series of publications about using the Apache ZooKeeper for building configuration management solutions for a distributed system. It focuses on implementing a tool for loading initial configuration data into a fresh ZooKeeper ensemble.
One of the steps towards building a successful distributed software system is establishing effective configuration management. It is a complex engineering process which is responsible for planning, identifying, tracking and verifying changes in the software and its configuration as well as maintaining configuration integrity throughout the life cycle of the system.
Let's consider how to store and manage configuration settings of the entire system and its components using Apache ZooKeeper, a high-performance coordination service for distributed applications.
