BiteTheDDDDt opened a new pull request #7221:
URL: https://github.com/apache/incubator-doris/pull/7221
## Proposed changes
`select bitmap_xor(bitmap_from_string('1'), bitmap_from_string('1,1'));`
`https://github.com/greg7mdp/parallel-hashmap`
```
The btree containers are direct ports from Abseil, and should behave exactly
the same as the Abseil ones, modulo small differences (such as supporting
std::string_view instead of absl::string_view, and being forward declarable).
When btrees are mutated, values stored within can be moved in memory. This
means that pointers or iterators to values stored in btree containers can be
invalidated when that btree is modified. This is a significant difference with
std::map and std::set, as the std containers do offer a guarantee of pointer
stability. The same is true for the 'flat' hash maps and sets.
