> Nested scan can be performed by Calcite engine, for example, in case of UNION
> ALL, when the first table scan is completed (and {{{}downstream().end(){}}})
> method is invoked and UNION ALL operator proceed to the next table scan.
> Reproducer:
> {code:java}
> public void testPerformanceStatisticsNestedScan() throws Exception {
> sql(grid(0), "CREATE TABLE test_perf_stat_nested (a INT) WITH
> template=REPLICATED");
> sql(grid(0), "INSERT INTO test_perf_stat_nested VALUES (0), (1), (2),
> (3), (4)");
> startCollectStatistics();
> sql(grid(0), "SELECT * FROM test_perf_stat_nested UNION ALL SELECT * FROM
> test_perf_stat_nested");
> }{code}
> Fails on:
