Constructor Detail

ChangeEvent

public ChangeEvent(ChangeIdentifier id,
                   Long txId,
                   Integer seq,
                   Metadata metadata,
                   Event event)

Method Detail

getId

public ChangeIdentifier getId()

A unique change identifier that identifies this change record. It can be used to query changes from this change onward.

Returns:

change identifier

getTxId

public Long getTxId()

A number identifying which transaction the change happened in, unique in combination with seq. Transaction identifiers are not continuous (some transactions, such as system and schema commands, are not recorded in change data capture and cause gaps in the transaction identifiers).

Returns:

transaction id

getSeq

public Integer getSeq()

A number used for ordering changes that happened in the same transaction. The order of changes observed in the output does not necessarily correspond to the order in which changes were applied during the transaction.

Returns:

sequence

getMetadata

public Metadata getMetadata()

Other useful information about the transaction.

Returns:

metadata

getEvent

public Event getEvent()

Details about the actual data change.

Returns:

event

equals

public boolean equals(Object o)

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()
