Seems that `velox` will force align the data:
```
FOLLY_ALWAYS_INLINE int64_t sizeAlign(int64_t size) {
const auto remainder = size % alignment_;
return (remainder == 0) ? size : (size + alignment_ - remainder);
}
void* MemoryPoolImpl::allocate(int64_t size) {
CHECK_AND_INC_MEM_OP_STATS(Allocs);
const auto alignedSize = sizeAlign(size);
reserve(alignedSize);
void* buffer = allocator_->allocateBytes(alignedSize, alignment_);
if (FOLLY_UNLIKELY(buffer == nullptr)) {
release(alignedSize);
VELOX_MEM_ALLOC_ERROR(fmt::format(
"{} failed with {} bytes from {}", __FUNCTION__, size, toString()));
}
return buffer;
}
```
