Examples of ZNRecordSerializer

com.linkedin.helix.manager.zk.ZNRecordSerializer
org.apache.helix.manager.zk.ZNRecordSerializer
org.apache.s4.comm.topology.ZNRecordSerializer
Utility to serialize/deserialize data in ZK.
Using Json format and Gson library. TODO: Explore other libraries like jackson much richer features. Gson needs no-arg constructor to work with without additional work
