> BoundedDataTestBase has potential problem when compression is enable, I'm
> sure there is a bug in this part of the code. But unfortunately, the test can
> pass now, because the generated data used in the test cannot be compressed by
> LZ4 (i.e. the compressed size is larger than the original size), which causes
> the branch of enable compression actually the same as disable compression, So
> the bug didn't surface.
> I think there are two steps of work that need to be done:
> 1. Fix incorrect code
> 2. Generate data that can be properly compressed
