Enum Class DataReplicationPolicy

java.lang.Object

java.lang.Enum<DataReplicationPolicy>

com.linkedin.venice.meta.DataReplicationPolicy

All Implemented Interfaces:

Serializable, Comparable<DataReplicationPolicy>, Constable

public enum DataReplicationPolicy
extends Enum<DataReplicationPolicy>

The data replication policy determines which fabric to use for sending real-time writes from clients and where to direct servers for real-time data consumption. If active-active replication is enabled, the data replication policy is bypassed, as writes are sent to the local fabric.

Enum Constant Details

NON_AGGREGATE

public static final DataReplicationPolicy NON_AGGREGATE

Default value. Samza job per colo pushes to local real-time topic. Leader SNs replicate data to local version topic.

AGGREGATE

public static final DataReplicationPolicy AGGREGATE

Single Samza job or Samza job per colo pushes to real-time topic in parent colo. Leader SNs in each colo replicate data from remote real-time topic to local version topic.

NONE

@Deprecated
public static final DataReplicationPolicy NONE

Deprecated.

ACTIVE_ACTIVE

@Deprecated
public static final DataReplicationPolicy ACTIVE_ACTIVE

Deprecated.

Method Details

values

public static DataReplicationPolicy[] values()
