Example 6 with LogTruncation

use of org.apache.kafka.clients.consumer.internals.SubscriptionState.LogTruncation in project kafka by apache.

the class SubscriptionStateTest method testMaybeCompleteValidation.

@Test
public void testMaybeCompleteValidation() {
    Node broker1 = new Node(1, "localhost", 9092);
    state.assignFromUser(Collections.singleton(tp0));
    int currentEpoch = 10;
    long initialOffset = 10L;
    int initialOffsetEpoch = 5;
    SubscriptionState.FetchPosition initialPosition = new SubscriptionState.FetchPosition(initialOffset, Optional.of(initialOffsetEpoch), new Metadata.LeaderAndEpoch(Optional.of(broker1), Optional.of(currentEpoch)));
    state.seekUnvalidated(tp0, initialPosition);
    assertTrue(state.awaitingValidation(tp0));
    Optional<LogTruncation> truncationOpt = state.maybeCompleteValidation(tp0, initialPosition, new EpochEndOffset().setLeaderEpoch(initialOffsetEpoch).setEndOffset(initialOffset + 5));
    assertEquals(Optional.empty(), truncationOpt);
    assertFalse(state.awaitingValidation(tp0));
    assertEquals(initialPosition, state.position(tp0));
}

Example 7 with LogTruncation
