Personally I don't understand how you can call a database robust if it can't scale down nodes after you scaled them up once. What am I supposed to do if I ever deploy to 50 nodes and then it turns out that I only need 5. Shut the business down? Pay to run database servers forever that I don't even need anymore? Also the database configuration has a lot of gotchas and is very opaque. You might be waiting for 30sec for your CLI to connect to your localhost cluster of two processes and you have no idea what is happening or why it is taking that long. It just never felt so safe and robust as people claim it to be. I don't know, these were just my findings on the brief tests I did with it.

Also you better get familiar with a whole bunch of hidden "knobs" that are apparently configurable and very important somewhere and then get printed out into xml logs but of course there is no log viewer so you have to write your own. Maybe this isn't a problem for large companies but I'm providing feedback as a single user here.

I also don't understand how people can praise the c++ DSL. They should rewrite that into standard c++ coroutines as soon as possible so their entire build and dev environment isn't so hard to understand. As a user of open source software I generally like to be able to debug through the projects I use and figure out problems I have. It's much harder when a project uses their own custom language. I certainly tried to set it all up correctly but there always seemed to be some problems in regards to Intellisense within the IDE.

What is this process describing, and how does it differ from what you were trying to do?

They are using the term "machine" and "process" in multiple conflicting meanings I think. I mean maybe they improved this since I used it 1.5 years ago but I kind of doubt it.

If I remember correctly there is a definite problem if you remove one of the processes that end up guaranteeing your configured redundancy mode. So then suddenly your entire cluster is inoperable. Yes really, I think it doesn't even properly respond to cli commands anymore and shows nodes as simply missing. Oh and suddenly those long wait times for your cli commands are really starting to bother you... I don't really want to talk more about it because it's been a while but I just wanted to make the point that the user experience was quite bad.

This is not true.

We've run fdb in production for several years at this point. We have dramatically scaled production clusters up and down.
