Example 96 with JobConfig

use of com.hazelcast.jet.config.JobConfig in project hazelcast-jet by hazelcast.

the class JobRestartWithSnapshotTest method when_nodeDown_then_jobRestartsFromSnapshot.

public void when_nodeDown_then_jobRestartsFromSnapshot(boolean twoStage) throws Exception {
    /* Design of this test:

        It uses random partitioned generator of source events. The events are Map.Entry(partitionId, timestamp).
        For each partition timestamps from 0..elementsInPartition are generated.

        We start the test with two nodes and localParallelism(1) for source. Source instances generate items at
        the same rate of 10 per second: this causes one instance to be twice as fast as the other in terms of
        timestamp. The source processor saves partition offsets similarly to how streamKafka() and streamMap()
        do.

        After some time we shut down one instance. The job restarts from snapshot and all partitions are restored
        to single source processor instance. Partition offsets are very different, so the source is written in a way
        that it emits from the most-behind partition in order to not emit late events from more ahead partitions.

        Local parallelism of InsertWatermarkP is also 1 to avoid the edge case when different instances of
        InsertWatermarkP might initialize with first event in different frame and make them start the no-gap
        emission from different WM, which might cause the SlidingWindowP downstream to miss some of the
        first windows.

        The sink writes to an IMap which is an idempotent sink.

        The resulting contents of the sink map are compared to expected value.
