Specified by:

preSnapshotStart in interface OffsetContext

preSnapshotCompletion

public void preSnapshotCompletion()

Specified by:

preSnapshotCompletion in interface OffsetContext

postSnapshotCompletion

public void postSnapshotCompletion()

Specified by:

updateWalPosition

public void updateWalPosition(Lsn lsn,
 Lsn lastCompletelyProcessedLsn,
 Instant commitTime,
 Long txId,
 Long xmin,
 TableId tableId)

updateWalPosition

public void updateWalPosition(Lsn lsn,
 Lsn lastCompletelyProcessedLsn,
 Instant commitTime,
 Long txId,
 Long xmin)

update wal position for lsn events that do not have an associated table or schema

updateCommitPosition

public void updateCommitPosition(Lsn lsn,
 Lsn lastCompletelyProcessedLsn)

hasLastKnownPosition

boolean hasLastKnownPosition()

hasCompletelyProcessedPosition

boolean hasCompletelyProcessedPosition()

lsn

Lsn lsn()

lastCompletelyProcessedLsn

Lsn lastCompletelyProcessedLsn()

lastCommitLsn

Lsn lastCommitLsn()

getStreamingStoppingLsn

Lsn getStreamingStoppingLsn()

Returns the LSN that the streaming phase should stream events up to or null if a stopping point is not set. If set during the streaming phase, any event with an LSN less than the stopping LSN will be processed and once the stopping LSN is reached, the streaming phase will end. Useful for a pre-snapshot catch up streaming phase.

setStreamingStoppingLsn

public void setStreamingStoppingLsn(Lsn streamingStoppingLsn)

xmin

Long xmin()

toString

public String toString()

Overrides:

toString in class Object
