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
