A FeatureBase Cluster is a distributed system that is maintained by
etcd which runs on each node.
The system requires at least three nodes to maintain data consistency and fault tolerances.
Table of contents
When you choose to migrate data from one cluster to another, the destination cluster resources (HD size, memory and processor cores) can be:
- identical to the source cluster
- larger than the source cluster
Clusters cannot be migrated to systems with less resources than the source.
Cluster metrics are a subset of FeatureBase metrics.
