Class DatanodeSchemaTwoDBDefinition

java.lang.Object

org.apache.hadoop.ozone.container.metadata.AbstractDatanodeDBDefinition

org.apache.hadoop.ozone.container.metadata.DatanodeSchemaTwoDBDefinition

All Implemented Interfaces:

org.apache.hadoop.hdds.utils.db.DBDefinition, org.apache.hadoop.hdds.utils.db.DBDefinition.WithMapInterface

public class DatanodeSchemaTwoDBDefinition
extends AbstractDatanodeDBDefinition
implements org.apache.hadoop.hdds.utils.db.DBDefinition.WithMapInterface

This class defines the RocksDB structure for datanodes following schema version 2, where the block data, metadata, and transactions which are to be deleted are put in their own separate column families.
