PhysicalStreamBuilder(StartPhysicalReplicationCallback startCallback)

Method Summary

Modifier and Type	Method	Description
@Nullable String	getSlotName()	Replication slots provide an automated way to ensure that the master does not remove WAL segments until they have been received by all standbys, and that the master does not remove rows which could cause a recovery conflict even when the standby is disconnected.
LogSequenceNumber	getStartLSNPosition()
int	getStatusInterval()	Specifies the number of millisecond between status packets sent back to the server.
protected ChainedPhysicalStreamBuilder	self()
PGReplicationStream	start()	Open physical replication stream.

Constructor Details

PhysicalStreamBuilder

public PhysicalStreamBuilder(StartPhysicalReplicationCallback startCallback)

Parameters:

startCallback - not null callback that should be execute after build parameters for start replication

Method Details

self

protected ChainedPhysicalStreamBuilder self()

Specified by:

self in class AbstractStreamBuilder<ChainedPhysicalStreamBuilder>

start

public PGReplicationStream start()
                          throws SQLException

Description copied from interface: ChainedPhysicalStreamBuilder

Open physical replication stream.

Specified by:

start in interface ChainedPhysicalStreamBuilder

Returns:

not null PGReplicationStream available for fetch wal logs in binary form

Throws:

SQLException - on error

getSlotName

public @Nullable String getSlotName()

Description copied from interface: CommonOptions

Replication slots provide an automated way to ensure that the master does not remove WAL segments until they have been received by all standbys, and that the master does not remove rows which could cause a recovery conflict even when the standby is disconnected.

Specified by:

getSlotName in interface CommonOptions

Returns:

nullable replication slot name that already exists on server and free.

getStartLSNPosition

public LogSequenceNumber getStartLSNPosition()

Specified by:

getStartLSNPosition in interface CommonOptions

Returns:

the position to start replication. This cannot be null.

getStatusInterval

public int getStatusInterval()

Description copied from interface: CommonOptions

Specifies the number of millisecond between status packets sent back to the server. This allows for easier monitoring of the progress from server. A value of zero disables the periodic status updates completely, although an update will still be sent when requested by the server, to avoid timeout disconnect. The default value is 10 seconds.

Specified by:

getStatusInterval in interface CommonOptions

Returns:

the current status interval
