      Description

      The default values for TokuDB tables is optimized towards slow spinning disk. For 8.0, we want to change to values that are more friendly for SSD. Currently we understand these to be:
      tokudb_block_size=1M (from 4M)
      tokudb_read_block_size=64K (unchanged)
      tokudb_fanout=128 (from 16)
