ReplicationSlot

public ReplicationSlot(String slotName,
                       ReplicationType replicationType,
                       LogSequenceNumber consistentPoint,
                       @Nullable
                       String snapshotName,
                       @Nullable
                       String outputPlugin)

Method Detail

getSlotName

public String getSlotName()

Returns the replication slot name.

Returns:

the slot name

getReplicationType

public ReplicationType getReplicationType()

Replication type of the slot created, PHYSICAL or LOGICAL.

Returns:

ReplicationType, PHYSICAL or LOGICAL

getConsistentPoint

public LogSequenceNumber getConsistentPoint()

Returns the LSN at which we became consistent.

Returns:

LogSequenceNumber at consistent_point

getSnapshotName

@Nullable
public String getSnapshotName()

Returns the exported snapshot name at the point of replication slot creation.

As long as the exporting transaction remains open, other transactions can import its snapshot, and thereby be guaranteed that they see exactly the same view of the database that the first transaction sees.

Returns:

exported snapshot_name

getOutputPlugin

@Nullable
public String getOutputPlugin()

Returns the output plugin used on slot creation.

Returns:

the output plugin used on slot creation
