🌱 Brent Simmons Sync Rules

The Rules for merging notes

1. Conflicts are not permitted.
2. A note should merge at the property level. (If you change note text on your day phone > and a note’s tags on your night phone, both phones should get both changes.)
3. Real time determines which change wins.
4. A client doesn’t have to be up-to-date before it can push changes to the server.
5. The order of calls to the server must not matter.
6. It’s not important to keep a history of changes.

I think a good syncing system has four attributes:

1. It does what the user expects.
2. It’s efficient.
3. It resists failures.
4. It continues to work.
