Thanks for posting this. It's worth taking a look at what some other systems have done as well. I just spent some time looking at Ceph, and sounds like they ran into similar issues and moved to a raw-disk based idea: http://www.slideshare.net/sageweil1/bluestore-a-new-faster-storage-backend-for-ceph-63311181
I'll keep investigating how their actual allocator works. I dont think a raw disk is usable for Kudu, but maybe some ideas would translate. -Todd On Wed, Oct 5, 2016 at 1:53 PM, Adar Dembo <[email protected]> wrote: > I've written up a doc that summarizes two major issues related to hole > punching in Kudu's log block manager, as well as some approaches for > fixing them.
