    this.stormConfig = stormConfig;
    this.stellarProcessor = new StellarProcessor();
    this.fileNameFormat.prepare(stormConfig, topologyContext);
    if (syncPolicy != null) {
        // if the user has specified the sync policy, we don't want to override their wishes.
        syncPolicyCreator = new ClonedSyncPolicyCreator(syncPolicy);
    } else {
        // if the user has not, then we want to have the sync policy depend on the batch size.
        syncPolicyCreator = (source, config) -> new CountSyncPolicy(config == null ? 1 : config.getBatchSize(source));
    }
}

    new FileSizeRotationPolicy(10000, Units.MB), new CountSyncPolicy(1), testFormat, callback);
    handler.rotateOutputFile();
    // Function should ensure rotation actions and callback are called.
    verify(rotAction1).execute(any(), any());
    verify(rotAction2).execute(any(), any());
    verify(callback).removeKey();
}

Example 5 with CountSyncPolicy

@Test
public void testClonedPolicy() {
    CountSyncPolicy basePolicy = new CountSyncPolicy(5);
    ClonedSyncPolicyCreator creator = new ClonedSyncPolicyCreator(basePolicy);
    // ensure cloned policy continues to work and adheres to the contract: mark on 5th call.
    SyncPolicy clonedPolicy = creator.create("blah", null);
    for (int i = 0; i < 4; ++i) {
        assertFalse(clonedPolicy.mark(null, i));
    }
    assertTrue(clonedPolicy.mark(null, 5));
    // reclone policy and ensure it adheres to the original contract.
    clonedPolicy = creator.create("blah", null);
    assertFalse(clonedPolicy.mark(null, 0));
