Replication slot name.

Returns:

the slot name

getReplicationType

public ReplicationType getReplicationType()

Replication type of the slot created, might be PHYSICAL or LOGICAL.

Returns:

ReplicationType, PHYSICAL or LOGICAL

getConsistentPoint

public LogSequenceNumber getConsistentPoint()

LSN at which we became consistent.

Returns:

LogSequenceNumber with the consistent_point

getSnapshotName

public String getSnapshotName()

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.
