Replication Concepts used in Vertica Database

  • Replication the Vertica process of storing identical copies of data across all nodes in a cluster.
  • Replication
  • will offer H.A.(high avalibility) to our cluster by creating buddy projections across all nodes.
  • this way every node will have a copy of the other node projections enabling us to recover from a node loss.
  • Replication creates and stores identical copies of projections for small tables across all nodes in the cluster.
  • Replication is best used for a small projection, copy the full projection to each node.

    Example : Vertica Replication Vertica Replication

    In the image we can see that we have 4 projections that are replicated across all nodes.
