Dynamic Configuration Management with Netflix Archaius and Apache ZooKeeper, Property-Files, JMX

Wednesday, April 13th, 2016

Though having written about other configuration management libraries for Java before, I would like to demonstrate another one today: Netflix Archaius.

Archaius offers some nice features like dynamic typed properties, thread-safe operations, an event system for property changes/updates, a JMX MBean to read and update properties and adaptors for a variety of dynamic configuration sources like Amazon DynamoDB, JDBC, URLs and Apache ZooKeeper.

In the following tutorial I’d like to demonstrate how to read and update application configuration properties with Archaius and data sources like property-files, system-properties, JMX and Apache ZooKeeper.


Creating a XMPP Chat Bot with Apache Camel

Loading values from different sources like property-files, environment variables, command-line-arguments or system properties, specifying default values, mapping arbitrary types or collections, merging configurations and using the Java Bean Validation standard aka JSR-303.
