In social media analytics:

  • Cassandra is used by many social media providers to recognize the data and gives recommendations to their users.

Apache Cassandra seed node:

  • Seeds are used to discover the cluster in the start up period.
  • The seed node designation has no purpose other than bootstrapping the gossip process for new nodes joining the cluster.
  • Seed nodes could not be a single point of failure, nor they have do any other purpose in cluster operations except the bootstrapping of nodes.
  • In cluster formation, nodes are verify “join” and each other.
  • However, they do not join any node which respects the protocol.Risks:old partitioned replicas, different clusters, even malicious nodes, so on. So a cluster can be defined by some starting nodes contain at clear addresses and it can be reference for that cluster for any new nodes to join in trust-table way.
  • After some time the seed nodes can go away, then the cluster will keep on.
