示例1: open
import java.util.Collections; //導入方法依賴的package包/類
@Override
public void open(Map conf, TopologyContext context, SpoutOutputCollector collector) {
initialized = false;
this.context = context;
// Spout internals
this.collector = collector;
numUncommittedOffsets = 0;
// Offset management
firstPollOffsetStrategy = kafkaSpoutConfig.getFirstPollOffsetStrategy();
// with AutoCommitMode, offset will be periodically committed in the background by Kafka consumer
// consumerAutoCommitMode = kafkaSpoutConfig.isConsumerAutoCommitMode();
//永遠設置為false
consumerAutoCommitMode = false;
// Retries management
retryService = kafkaSpoutConfig.getRetryService();
if (!consumerAutoCommitMode) { // If it is auto commit, no need to commit offsets manually
commitTimer = new Timer(TIMER_DELAY_MS, kafkaSpoutConfig.getOffsetsCommitPeriodMs(), TimeUnit.MILLISECONDS);
}
refreshSubscriptionTimer = new Timer(TIMER_DELAY_MS, kafkaSpoutConfig.getPartitionRefreshPeriodMs(), TimeUnit.MILLISECONDS);
acked = new HashMap<>();
emitted = new HashSet<>();
waitingToEmit = Collections.emptyListIterator();
LOG.info("Kafka Spout opened with the following configuration: {}", kafkaSpoutConfig);
