> Issue Type: Improvement

>
> Currently we use a pseudo-estimated value to calculate the scan size which
> does not take the actual size of data into account.
> HBase, through {{o.a.h.h.client.HBaseAdmin.getClusterStatus()}}, provides a
> way to retrieve the actual data size of each region. We can use this to
> approximate the size of scan and use it to improve the scan parallelization.
