Interface ReplicationRequest.PhysicalReplicationRequestBuilder

All Superinterfaces:

ReplicationRequest.PhysicalReplicationStep1, ReplicationRequest.PhysicalReplicationStep2, ReplicationRequest.WithSlotName, ReplicationRequest.WithStartPosition, ReplicationRequest.WithStatusInterval

Enclosing class:

ReplicationRequest

public static interface ReplicationRequest.PhysicalReplicationRequestBuilder
extends ReplicationRequest.PhysicalReplicationStep1, ReplicationRequest.PhysicalReplicationStep2, ReplicationRequest.WithSlotName, ReplicationRequest.WithStartPosition, ReplicationRequest.WithStatusInterval

Fluent builder interface to configure a physical replication stream.

Method Summary

Modifier and Type	Method and Description
ReplicationRequest	build() Returns the physical ReplicationRequest.
ReplicationRequest.PhysicalReplicationRequestBuilder	slotName(String slotName) 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.
ReplicationRequest.PhysicalReplicationRequestBuilder	startPosition(LogSequenceNumber lsn) Specify start position from which backend will start stream changes.
ReplicationRequest.PhysicalReplicationRequestBuilder	statusInterval(Duration interval) Specifies the number of time between status packets sent back to the server.

Method Detail

slotName

ReplicationRequest.PhysicalReplicationRequestBuilder slotName(String slotName)

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:

slotName in interface ReplicationRequest.PhysicalReplicationStep1

Specified by:

slotName in interface ReplicationRequest.WithSlotName

Parameters:

slotName - not null replication slot already exists on server

Returns:

this builder

startPosition

ReplicationRequest.PhysicalReplicationRequestBuilder startPosition(LogSequenceNumber lsn)

Specify start position from which backend will start stream changes. If parameter will not specify, streaming starts from restart_lsn. For more details see pg_replication_slots description.

Specified by:

startPosition in interface ReplicationRequest.PhysicalReplicationStep2

Specified by:

startPosition in interface ReplicationRequest.WithStartPosition

Parameters:

lsn - not null position from which need start replicate changes

Returns:

this builder

statusInterval

ReplicationRequest.PhysicalReplicationRequestBuilder statusInterval(Duration interval)

Specifies the number of time 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:

statusInterval in interface ReplicationRequest.WithStatusInterval

Parameters:

interval - positive time

Returns:

this builder.

build

ReplicationRequest build()

Returns the physical ReplicationRequest.

Returns:

the physical ReplicationRequest.
