Some notes on the database schema.
|
|
|
|
We don't use null, only empty strings. This is easier to work with on the go
|
|
side.
|
|
|
|
The main table is honks. This stores both locally created honks and incoming
|
|
ActivityPub notes converted to honks. It is important to differentiate the two
|
|
cases so that we don't accidentally publish external honks in the public web
|
|
view. (Previously this was accomplished via separate tables. That made some
|
|
queries more difficult, but I think it's possible to workaround this. It would
|
|
be considerably safer.) The honker column will be empty for local honks.
|
|
|
|
The what column further refines the type of honk. If a reply, tonk. If
|
|
deleted, zonk. If shared, bonk. In particular for the case of bonk, there
|
|
aren't enough columns to store original honker and bonker. This seems to work
|
|
out okay though.
|
|
|
|
The honkers table is used to manage follows and followers. The flavor column
|
|
describes what. 'sub' is a follow. We have subscribed to their newsletter.
|
|
'dub' is a follower. They get dubbed whenever we honk. We also use this table
|
|
to store public keys for anyone we interact with. This is regrettable.
|
|
|
|
The xid column generally corresponds to ActivityPub id. For local honks, it
|
|
will be a short string, not a complete URL.
|
|
|
|
Such explanation would be less necessary were the tables not misused for
|
|
multiple purposes. Will probably split them apart again soon.
|
|
|
|
Note that some logical seeming joins won't work. The honker column of honks
|
|
does not have a correspondng entry in the honkers table, since we frequently
|
|
receive messages from people we don't follow. Should we track everybody whose
|
|
identity crosses our path? This seems unnecessary. The honkers table is more
|
|
like a mapping of active relationships, not a directory of all peoples.
|
|
|
|
Some deduping of honks is performed. Known shortcoming: only the first bonk is
|
|
recorded. Subsequent bonks, even by different actors, are ignored. Bonus
|
|
shortcoming: we download such bonks every time.
