Also reproduced the sympton in this issue using C++, about the same chance
as above:
```
TEST(AsofJoinTest, Flaky2) {
std::vector<TypeHolder> left_types = {int64()};
auto left_batch = ExecBatchFromJSON(left_types, R"([[1], [2], [3]])");
std::vector<TypeHolder> right_types = {utf8(), int64()};
auto right_batch = ExecBatchFromJSON(right_types, R"([["Z", 2], ["B", 3],
["A", 4]])");
Declaration left{"exec_batch_source",
ExecBatchSourceNodeOptions(schema({field("on", int64())}),
{std::move(left_batch)})};
Declaration right{
"exec_batch_source",
ExecBatchSourceNodeOptions(schema({field("colVals", utf8()),
field("on", int64())}),
{std::move(right_batch)})};
AsofJoinNodeOptions asof_join_opts({{{"on"}, {}}, {{"on"}, {}}}, 1);
Declaration asof_join{"asofjoin", {left, right}, asof_join_opts};
ASSERT_OK_AND_ASSIGN(auto result, DeclarationToExecBatches(asof_join));
std::vector<TypeHolder> exp_types = {int64(), utf8()};
auto exp_batch = ExecBatchFromJSON(exp_types, R"([[1, "Z"], [2, "Z"], [3,
"B"]])");
AssertExecBatchesEqualIgnoringOrder(result.schema, {exp_batch},
result.batches);
}
```
