| Some questions come to mind:
|
| How does research at facebook work? Is there some group that site
| around researching then goes to teams and says "implement this!"
| How does that dynamic work? My company actually has that going
| on, I find it annoying, were often not aligned imo.
|
| Why share this with a research paper format? It makes it feel
| unapproachable. Personally find it hard to follow like this.

| I don't get how it handles the replica assignments? If you have
| 10 servers and 1000 shards, 2000 replicas, you would have to much
| overlap of replica ownership between the 10 servers. Somehow you
| would want the replica assigner to know how to do this
| efficiently (have replicas split between 5 and 5 with no overlap
| in this case) I think every operation requires moving shards
| otherwise
|
| low effort but this feels a little like https://xkcd.com/927/
