Example 26 with KafkaMetric

use of org.apache.kafka.common.metrics.KafkaMetric in project kafka by apache.

the class MeteredWindowStoreTest method shouldBackwardFetchAllFromInnerStoreAndRecordFetchMetrics.

@Test

    // recorded on close;
    store.backwardFetchAll(ofEpochMilli(1), ofEpochMilli(1)).close();
    // it suffices to verify one fetch metric since all fetch metrics are recorded by the same sensor
    // and the sensor is tested elsewhere
