Re: [DISCUSS] Should we support upgrading 1.4 -> 1.6 w/o going through 1.5?
We initially tried to set it up as a stand-alone utility but eventually
gave up. In order to properly do the upgrade, you concurrently need to run
whatever upgrade code concurrently with a tablet server hosting !METADATA
and a tablet server that can replay WALs. We ended up duplicating a lot of
logic already present in master before scrapping that plan. An alternative
would have been to try to build on MAC, but that was also non-trivial to
deploy, so we spliced the code into the existing upgrade path. How do you
feel about that, Drew?
