[Defect] Inconsistent results using SophireadStream

[suannchong]

When running SophireadStream on the same file same machine, inconsistent results were observed.

Chen's comments:

• It is possible for SophireadStream to generate different results because the performance of the processing thread is not guaranteed to be the same between different runs. If you increase the batch size, the difference might become smaller.
• Alternatively, we need to implement a solution to deal with the tail of each batch size, which should help mitigate the issue.
