Examples of com.linkedin.helix.ZNRecord.merge()

com.linkedin.helix.ZNRecord.merge()
merge functionality is used to merge multiple znrecord into a single one. This will make use of the id of each ZNRecord and append it to every key thus making key unique. This is needed to optimize on the watches. @param record
