> 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
