Vertica Database Replication Concepts
November 27, 2014
Replication the Vertica process of storing identical copies of data across all nodes in a cluster.
- will offer H.A.(high availability) 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.
In the image we can see that we have 4 projections that are replicated across all nodes.
