Configuration

public Configuration(boolean useAutoRebuild,
                     boolean useAutoReconnect,
                     boolean useAutoStart,
                     boolean useAutoConnect)

Method Detail

autoStart

public static DBDatabaseCluster.Configuration autoStart()

Use for a database that does not automatically rebuild the data when restarting the cluster nor reconnect quarantined databases after an error but does automatically start synchronising databases.

Returns:

a autostart configuration

manual

@Deprecated
public static DBDatabaseCluster.Configuration manual()

Deprecated.

This version of manual will automatically start the cluster, use autoStart() instead

Use for a database that does not automatically rebuild the data when restarting the cluster nor reconnect quarantined databases after an error.

Returns:

a manual configuration

fullyManual

public static DBDatabaseCluster.Configuration fullyManual()

Use for a database that does not automatically rebuild the data when restarting the cluster nor reconnect quarantined databases after an error.

The database will not be started nor will databases in the previous cluster instance be re-added.

Returns:

a manual configuration

autoRebuild

public static DBDatabaseCluster.Configuration autoRebuild()

A configuration that will try to restore the data from the previous instance of this cluster.

the TrackedTable list will also be rebuilt.

Auto-rebuild will automatically reload the tracked tables, connect to the authoritative database of the previous instance of this cluster, and reload the data for the tracked and required tables. This provides continuity of schema and data between instances of the cluster and removes the need to fully specify the schema within a DataRepo or configuration file.

Equivalent to new Configuration(true, false, true, false)

Returns:

an auto-rebuild configuration

autoReconnect

public static DBDatabaseCluster.Configuration autoReconnect()

A configuration that will try to connect quarantined databases will the cluster is running.

the TrackedTable list will also be rebuilt.

Auto-reconnect instructs the cluster to reconnect to any cluster members disconnected during processing. This includes databases that could not be connected to, and those that were quarantined due to errors.

Reconnected databases will be synchronized before use.

Equivalent to new Configuration(false, true, true, false)

Returns:

an auto-reconnect configuration

autoRebuildAndReconnect

@Deprecated
public static DBDatabaseCluster.Configuration autoRebuildAndReconnect()

Deprecated.

despite the method name, this will also start the cluster. Use autoRebuildReconnectAndStart() instead

A configuration that will try to restore the data from the previous instance of this cluster AND try to connect quarantined databases will the cluster is running. Equivalent to new Configuration(true, true, true, false)

Returns:

an auto-rebuild and reconnect configuration

autoRebuildReconnectAndStart

public static DBDatabaseCluster.Configuration autoRebuildReconnectAndStart()

A configuration that will try to restore the data from the previous instance of this cluster AND try to connect quarantined databases will the cluster is running. Equivalent to new Configuration(true, true, true, false)

Returns:

an auto-rebuild and reconnect configuration

isUseAutoRebuild

public boolean isUseAutoRebuild()

Auto-rebuild will automatically reload the tracked tables, connect to the authoritative database of the previous instance of this cluster, and reload the data for the tracked and required tables. This provides continuity of schema and data between instances of the cluster and removes the need to fully specify the schema within a DataRepo or configuration file.

Returns:

TRUE if the cluster will try to reload data from the previous version of the cluster.

isUseAutoReconnect

public boolean isUseAutoReconnect()

Auto-reconnect instructs the cluster to reconnect to any cluster members disconnected during processing. This includes databases that could not be connected to, and those that were quarantined due to errors. Reconnected databases will be synchronized before use.

Returns:

TRUE if the cluster will try to automatically reconnect and synchronize database while running.

isUseAutoStart

public boolean isUseAutoStart()

Auto-start instructs the cluster to immediately perform tasks required to make the cluster usable as a database. These tasks may include reloading the tracked tables and data of the previous instance, connecting to former members, synchronizing cluster members, starting the reconnection process, and more.

Returns:

the useAutoStart

isUseAutoConnect

public boolean isUseAutoConnect()

Auto-connect loads the list of cluster members from the previous instance. This provides continuity of membership and removes the need fully specify the members in code or configurations files.

Returns:

the useAutoConnect

withAutoRebuild

public DBDatabaseCluster.Configuration withAutoRebuild()

Auto-rebuild will automatically reload the tracked tables, connect to the authoritative database of the previous instance of this cluster, and reload the data for the tracked and required tables. This provides continuity of schema and data between instances of the cluster and removes the need to fully specify the schema within a DataRepo or configuration file.

Returns:

TRUE if the cluster will try to reload data from the previous version of the cluster.

withAutoReconnect

public DBDatabaseCluster.Configuration withAutoReconnect()

Auto-reconnect instructs the cluster to reconnect to any cluster members disconnected during processing. This includes databases that could not be connected to, and those that were quarantined due to errors. Reconnected databases will be synchronized before use.

Returns:

TRUE if the cluster will try to automatically reconnect and synchronize database while running.

withAutoStart

public DBDatabaseCluster.Configuration withAutoStart()

Auto-start instructs the cluster to immediately perform tasks required to make the cluster usable as a database. These tasks may include reloading the tracked tables and data of the previous instance, connecting to former members, synchronizing cluster members, starting the reconnection process, and more.

Returns:

the useAutoStart

withAutoConnect

public DBDatabaseCluster.Configuration withAutoConnect()

Auto-connect loads the list of cluster members from the previous instance. This provides continuity of membership and removes the need fully specify the members in code or configurations files.

Returns:

the useAutoConnect
