> so that if the node goes down and can't be brought back up, you can still
recover using the WAL.
I'm not sure I understand the reasoning behind that logic (admittedly, it's
"early"). Specifically, how would a failure of the local node be any different
than a failure of a non-local DN in the write pipeline? Also, aren't there
performance implications when using hflush to avoid the local node (not even
just the write side, but the read side would be unable to use SCR's when the
local DN doesn't have those blocks).
