Enum Class JeBackendCfgDefn.DbDurability

java.lang.Object

java.lang.Enum<JeBackendCfgDefn.DbDurability>

org.forgerock.opendj.server.config.meta.JeBackendCfgDefn.DbDurability

All Implemented Interfaces:

Serializable, Comparable<JeBackendCfgDefn.DbDurability>, java.lang.constant.Constable

Enclosing class:

JeBackendCfgDefn

public static enum JeBackendCfgDefn.DbDurability
extends Enum<JeBackendCfgDefn.DbDurability>

Defines the set of permissible values for the "db-durability" property.

Configures the durability level that will be used when committing a transaction.

High levels of durability offer a greater guarantee that the transaction is persisted to disk, but trade that off for lower performance.

Enum Constant Details

HIGH

public static final JeBackendCfgDefn.DbDurability HIGH

Write and synchronously flush the log on transaction commit. Transactions exhibit full durability and will not be lost if the application or operating system fails.

LOW

public static final JeBackendCfgDefn.DbDurability LOW

Do not write or synchronously flush the log on transaction commit. Database integrity will be maintained, but if the application or system fails, it is possible some number of the most recently committed transactions may be undone (lost) during recovery.

MEDIUM

public static final JeBackendCfgDefn.DbDurability MEDIUM

Write but do not synchronously flush the log on transaction commit. Database integrity will be maintained, but if the operating system fails, it is possible some number of the most recently committed transactions may be undone (lost) during recovery.
