ClusterSchema (PDI Engine 8.3.0.0-0.2.3 API)

java.lang.Object
- org.pentaho.di.core.changed.ChangedFlag
- - org.pentaho.di.cluster.ClusterSchema

所有已实现的接口:

Cloneable, ChangedFlagInterface, org.pentaho.di.core.variables.VariableSpace, org.pentaho.di.core.xml.XMLInterface, org.pentaho.di.repository.RepositoryElementInterface, org.pentaho.di.repository.RepositoryObjectInterface, org.pentaho.di.shared.SharedObjectInterface
```
public class ClusterSchema
extends ChangedFlag
implements Cloneable, org.pentaho.di.shared.SharedObjectInterface, org.pentaho.di.core.variables.VariableSpace, org.pentaho.di.repository.RepositoryElementInterface, org.pentaho.di.core.xml.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.
