示例1: processRecords

@Override
public void processRecords(List<Record> records, IRecordProcessorCheckpointer checkpointer) {
// Note: This method will be called even for empty record lists. This is needed for checking the buffer time
// threshold.

return;
}

throw new IllegalStateException("Record processor not initialized");
}
// Transform each Amazon Kinesis Record and add the result to the buffer
