Enum Class ScannerBase.ConsistencyLevel

java.lang.Object

java.lang.Enum<ScannerBase.ConsistencyLevel>

org.apache.accumulo.core.client.ScannerBase.ConsistencyLevel

All Implemented Interfaces:

Serializable, Comparable<ScannerBase.ConsistencyLevel>, Constable

Enclosing interface:

ScannerBase

public static enum ScannerBase.ConsistencyLevel
extends Enum<ScannerBase.ConsistencyLevel>

Consistency level for the scanner. The default level is IMMEDIATE, which means that this scanner will see keys and values that have been successfully written to a TabletServer. EVENTUAL means that the scanner may not see the latest data that was written to a TabletServer, but may instead see an older version of data. To use the EVENTUAL consistency level, ScanServer processes must be running. If not specifically configured, clients will use the default settings (ConfigurableScanServerSelector#PROFILES_DEFAULT). See ConfigurableScanServerSelector for information on how to configure the client.

Since:

2.1.0
