initialize

public void initialize(ExecutorService recordService,
 Transformations transformations)

Description copied from interface: RecordProcessor

Initialize the processor with objects created and managed by DebeziumEngine, which are needed for records processing.

Specified by:

initialize in interface RecordProcessor<R>

Parameters:

recordService - ExecutorService which allows to run processing of individual records in parallel.

transformations - chain of transformations to be applied on every individual record.

processRecords

public abstract void processRecords(List<org.apache.kafka.connect.source.SourceRecord> records)
                             throws Exception

Description copied from interface: RecordProcessor

Processes a batch of records provided by the source connector. Implementations are assumed to use DebeziumEngine.RecordCommitter to appropriately commit individual records and the batch itself.

Specified by:

processRecords in interface RecordProcessor<R>

Parameters:

records - List of SourceRecord provided by the source connector to be processed.

Throws:

Exception - Any exception is propagated to the caller.
