> pyarrow.lib.ArrowInvalid: straddling object straddles two block boundaries
(try to increase block size?)
This error might raise from the code below. How can I reproduce the problem
using C++ or Python code?
```c++
Status Chunker::ProcessWithPartial(std::shared_ptr<Buffer> partial,
std::shared_ptr<Buffer> block,
std::shared_ptr<Buffer>* completion,
std::shared_ptr<Buffer>* rest) {
if (partial->size() == 0) {
// If partial is empty, don't bother looking for completion
*completion = SliceBuffer(block, 0, 0);
*rest = block;
return Status::OK();
}
int64_t first_pos = -1;
RETURN_NOT_OK(boundary_finder_->FindFirst(std::string_view(*partial),
std::string_view(*block),
&first_pos));
if (first_pos == BoundaryFinder::kNoDelimiterFound) {
// No delimiter in block => the current object is too large for block
size
return StraddlingTooLarge();
} else {
*completion = SliceBuffer(block, 0, first_pos);
*rest = SliceBuffer(block, first_pos);
return Status::OK();
}
}
```
