Re: new log.dirs property (as opposed to log.dir)
The intention is to allow the use of multiple disks without RAID or
logical volume management. We have found that there are a lot of
downsides to RAID--in particular a huge throughput hit. Since we
already have a parallelism model due to partitioning and a fault
tolerance model with replication RAID doesn't actually buy much. With
this feature you can directly mount multiple disks as their own
directory and the server will randomly assign partitions to them.
Obviously this will only work well if there are enough high-throughput
partitions to make load balance evenly (e.g. if you have only one big
partition per server then this isn't going to work).
