    dag.edge(between(source, sink));
    Job job = jetInstance.newJob(dag);
    ICacheJet<Integer, Integer> sourceCache = jetInstance.getCacheManager().getCache(streamSourceName);
    range(0, ENTRY_COUNT).forEach(i -> sourceCache.put(i, i));
    assertSizeEventually(ENTRY_COUNT - 1, jetInstance.getList(streamSinkName));
