Method Detail

collectionId

public CollectionId collectionId()

Get the identifier of the collection to which this producer applies.

Returns:

the collection ID; never null

recordObject

public int recordObject(CollectionId id,
                        org.bson.Document object,
                        Instant timestamp)
                 throws InterruptedException

Generate and record one or more source records to describe the given object.

Parameters:

id - the identifier of the collection in which the document exists; may not be null

object - the document; may not be null

timestamp - the timestamp at which this operation is occurring

Returns:

the number of source records that were generated; will be 0 or more

Throws:

InterruptedException - if the calling thread was interrupted while waiting to submit a record to the blocking consumer

recordEvent

public int recordEvent(org.bson.Document oplogEvent,
                       org.bson.Document masterEvent,
                       Instant timestamp,
                       long txOrder)

timestamp - the timestamp at which this operation is occurring

txOrder - order of event in transaction; 0 for non-transactional event

Returns:

the number of source records that were generated; will be 0 or more

Throws:

InterruptedException - if the calling thread was interrupted while waiting to submit a record to the blocking consumer

recordEvent
