      Description

      Our current on-disk storage has a number of issues:

      • only writes to one local disk (need to scale to at least 12)
      • exhausts file descriptors quickly (see KUDU-56)
      • causes a ton of seeks at startup (KUDU-374)
      • has big latency stalls on write due to ext4 journal-related chunky writeback
      • doesn't support features we'll eventually want to support such as tiered storage
