    Description

      There is a need to calculate the amount of occupied disk space a database is consuming. This can be useful when calculating whether a database could be physically moved to a smaller disk size. Currently, only the on-disk file size is reported by dbstats, but this includes unoccupied blocks in files.
      To calculate this for WiredTiger, we can use block_reuse_bytes statistic per file, versus block_size.
