Example 1 with ProcessorStateManager

use of org.apache.kafka.streams.processor.internals.ProcessorStateManager in project kafka by apache.

the class TopologyTestDriver method setupTask.

@SuppressWarnings("deprecation")

    if (!partitionsByInputTopic.isEmpty()) {

        for (final TopicPartition topicPartition : partitionsByInputTopic.values()) {
            startOffsets.put(topicPartition, 0L);
        }
        consumer.updateBeginningOffsets(startOffsets);
        final ProcessorStateManager stateManager = new ProcessorStateManager(TASK_ID, Task.TaskType.ACTIVE, StreamsConfig.EXACTLY_ONCE.equals(streamsConfig.getString(StreamsConfig.PROCESSING_GUARANTEE_CONFIG)), logContext, stateDirectory, new MockChangelogRegister(), processorTopology.storeToChangelogTopic(), new HashSet<>(partitionsByInputTopic.values()));
        final RecordCollector recordCollector = new RecordCollectorImpl(logContext, TASK_ID, testDriverProducer, streamsConfig.defaultProductionExceptionHandler(), streamsMetrics);
        final InternalProcessorContext context = new ProcessorContextImpl(TASK_ID, streamsConfig, stateManager, streamsMetrics, cache);
        task = new StreamTask(TASK_ID, new HashSet<>(partitionsByInputTopic.values()), processorTopology, consumer, taskConfig, streamsMetrics, stateDirectory, cache, mockWallClockTime, stateManager, recordCollector, context, logContext);
        task.initializeIfNeeded();
        task.completeRestoration(noOpResetter -> {
        });
        task.processorContext().setRecordContext(null);
    } else {

Example 2 with ProcessorStateManager

use of org.apache.kafka.streams.processor.internals.ProcessorStateManager in project kafka by apache.

    final Metrics metrics = new Metrics();
    final LogContext logContext = new LogContext("test-stream-task ");
