> Project: Bookkeeper
> Issue Type: Improvement
> Reporter: Matteo Merli

> Fix For: 4.5.0
>
>
> 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.
