@pitrou I have a question regarding testing.
I need to write tests that allocate more than 14 GB of memory. I'm aware
that ARROW_LARGE_MEMORY_TESTS is intended to handle such scenarios. However,
would including such a test be problematic for CI builds? If so, what would be
the recommended approach?
Also, here is my test:
```c++
TEST_F(TestArray, TestBinaryViewAppendArraySliceMultipleBlocks) {
BinaryViewBuilder src_builder(pool_);
std::string a(std::numeric_limits<int32_t>::max(), 'a');
ASSERT_OK(src_builder.Append(a));
ASSERT_OK(src_builder.Append(a));
ASSERT_OK(src_builder.Append(a));
ASSERT_OK_AND_ASSIGN(auto src, src_builder.Finish());
ASSERT_OK(src->ValidateFull());
ArraySpan span;
span.SetMembers(*src->data());
BinaryViewBuilder dst_builder(pool_);
ASSERT_OK(dst_builder.AppendArraySlice(span, 0, src->length()));
ASSERT_OK_AND_ASSIGN(auto dst, dst_builder.Finish());
ASSERT_OK(dst->ValidateFull());
AssertArraysEqual(*src,*dst);
}
```
