public class Gossiper
extends AbstractUntypedActorWithMetering

Gossiper that syncs bucket store across nodes in the cluster.

It keeps a local scheduler that periodically sends Gossip ticks to itself to send bucket store's bucket versions to a randomly selected remote gossiper.

When bucket versions are received from a remote gossiper, it is compared with bucket store's bucket versions. Which ever buckets are newer locally, are sent to remote gossiper. If any bucket is older in bucket store, a gossip status is sent to remote gossiper so that it can send the newer buckets.

When a bucket is received from a remote gossiper, its sent to the bucket store for update.
