On: An Unlikely Database Migration

[_0c71]

I find the article a bit hard to follow. What were the actual requirements? I probably didnt understand all of this, but was the time spent on thinking about this more valuable than using a KV Store?

Yeah, I guess we could've laid that out earlier:

* our data is tiny and fits in RAM

* our data changes often

* we want to eventually get to an HA setup (3-5 etcd nodes now, a handful of backend server instances later)

* we want to be able to do blue/green deploys of our backend control server

* we want tests to run incredibly quickly (our current 8 seconds for all tests is too slow)

* we don't want all engineers to have to install Docker or specific DB versions on their dev machines
