Additional components of Cassandra

Now that we have discussed the read and write paths of an individual Apache Cassandra node, let's move up a level and consider how all of the nodes work together. Keeping data consistent and serving requests in a way that treats multiple machines as a single data source requires some extra engineering. Here we'll explore the additional components which make that possible.

Gossiper

Gossiper is a peer-to-peer communication protocol that a node uses to communicate with the other nodes in the cluster. When the nodes gossip with each other, they share information about themselves and retrieve information on a subset of other nodes in the cluster. Eventually, this allows a node to store...
