Examples of DbusEventStatsCollectorsPartitioner

com.linkedin.databus.core.monitoring.mbean.DbusEventStatsCollectorsPartitioner
DbusEventStats Merger that merges all inbound/outbound stats belonging to different physical partitions for the same database. Physical partitions belonging to different databases are grouped in different buckets and an dbusEventStatsMerger provided to merge all those belonging to the same database.
