> Key: IGNITE-19693
> URL: https://issues.apache.org/jira/browse/IGNITE-19693
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 3.0.0-beta1
> Reporter: Pavel Tupitsyn
> Assignee: Kirill Tkalenko
> Priority: Blocker
> Labels: ignite-3
> Fix For: 3.0.0-beta2
>
>
> * getAll does not preserve element order.
> * getAll does not return nulls for non-existent records.
> This is specified in Javadoc in
> [RecordView|https://github.com/apache/ignite-3/blob/0c68cbe3f016e508bd9d53ce5320c88acba1acff/modules/api/src/main/java/org/apache/ignite/table/RecordView.java#L56-L60]:
> {code}
> Records with all columns filled from the table. The order of collection
> elements is guaranteed to be the same as the order of {@code keyRecs}. If a
> record does not exist, the element at the corresponding index of the
> resulting collection is null.
> {code}
> Without those properties, *getAll* is not very useful: it is hard to
> correspond the results with the original collection.
> h2. Reproducer
> Add the following code to *ItTableApiContractTest*:
> {code:java}
> @Test
> public void testGetAll() {
> RecordView<Tuple> tbl =
> ignite.tables().table(TABLE_NAME).recordView();
> // recordView.insert(tx, Tuple.create().set("name",
> "k1").set("balance", 1));
> var recs = IntStream.range(1, 50)
> .mapToObj(i -> Tuple.create().set("name", "id_" + i *
> 2).set("balance", i * 2))
> .collect(Collectors.toList());
> tbl.upsertAll(null, recs);
> var keys = IntStream.range(1, 100)
> .mapToObj(i -> Tuple.create().set("name", "id_" + i))
> .collect(Collectors.toList());
> List<Tuple> res = (List<Tuple>) tbl.getAll(null, keys);
> assertNull(res.get(0));
> assertEquals(2L, res.get(1).longValue(0));
> assertEquals(100, res.size());
> }
> {code}
> Tuples are returned in random order, and only 50 of them, not 100
