tarantool/src/box/memtx_allocator.h
Lines 207 to 215 in 2502633
For memcs brin/skip indexes and for another upcoming features we need the following functionality:
- Ability to allocate arbitrary blocks of memory, not only memtx tuples;
- Coping of a block that is touched for writing, and that is referenced by a read view;
- Avoid CoW for blocks that is touched for writing, but isn't referenced by any read view.
