EventEmitterConfig uses a hash map to save exporter configs, key is event type: events/metrics, value is a hash map, key is
exporter name, value is a map of exporter configs.
A partitioner that reduces the number of connections a producer needs to make by
Specifying a subset percentage of total partitions to produce to
Randomly connecting to brokers and taking all partitions on that broker
until it has connected to the subset of partitions
Randomly produce to the recorded partitions
NOTE: This partitioner will not respect keys when determining the partition to be used.This is done so that keyed messages do not result in connections to every broker.
