      Description

      By configuring multiple journals, we can take advantage of the IO of multiple
      disks to increase the write throughput of a single bookie.

      Each journal will have its own journal and sync threads and writes will be
      assigned to a particular journal by hashing on the ledger id.

      In addition to using multiple physical disks, there can improvements even by
      using multiple journal on a single SSD device, because these disks can handle
      well multiple concurrent writes in different blocks of the disk.
