RecordMakers

public RecordMakers(SourceInfo source,
                    TopicSelector topicSelector,
                    BlockingConsumer<org.apache.kafka.connect.source.SourceRecord> recorder,

public RecordMakers.RecordsForCollection forCollection(CollectionId collectionId)

Obtain the record maker for the given table, using the specified columns and sending records to the given consumer.

Parameters:

collectionId - the identifier of the collection for which records are to be produced; may not be null

Returns:

the table-specific record maker; may be null if the table is not included in the connector
