- org.pentaho.di.core.changed.ChangedFlag
- - org.pentaho.di.cluster.ClusterSchema

All Implemented Interfaces:

Cloneable, ChangedFlagInterface, VariableSpace, XMLInterface, RepositoryElementInterface, RepositoryObjectInterface, SharedObjectInterface
```
public class ClusterSchema
extends ChangedFlag
implements Cloneable, SharedObjectInterface, VariableSpace, RepositoryElementInterface, XMLInterface
```
A cluster schema combines a list of slave servers so that they can be set altogether. It (can) also contain a number of performance tuning options regarding this cluster. For example options regarding communications with the master node of the nodes themselves come to mind.
