Example 1 with SnapshotValidationRecord

use of com.hazelcast.jet.impl.SnapshotValidationRecord in project hazelcast by hazelcast.

the class SnapshotLargeChunk_IntegrationTest method test_snapshotRestoreLargeChunk.

@Test
public void test_snapshotRestoreLargeChunk() {
    HazelcastInstance instance = createHazelcastInstance();
    DAG dag = new DAG();
    dag.newVertex("src", LargeStateP::new).localParallelism(1);
    Job job = instance.getJet().newJob(dag, new JobConfig().setProcessingGuarantee(ProcessingGuarantee.EXACTLY_ONCE).setSnapshotIntervalMillis(DAYS.toMillis(1)));
    assertJobStatusEventually(job, RUNNING);
    job.restart();
    assertJobStatusEventually(job, RUNNING);
    // assert that the snapshot exists and that the chunk was large enough
    IMap<Object, Object> map = instance.getMap(JobRepository.snapshotDataMapName(job.getId(), 0));
    SnapshotValidationRecord validationRec = (SnapshotValidationRecord) map.get(SnapshotValidationRecord.KEY);
    assertEquals(1, validationRec.numChunks());
    IntSummaryStatistics stats = map.values().stream().filter(v -> v instanceof byte[]).collect(summarizingInt(v -> ((byte[]) v).length));
    assertTrue("min=" + stats.getMin(), stats.getMin() > AsyncSnapshotWriterImpl.DEFAULT_CHUNK_SIZE);
