I can't comment about scaling to this size, but it should be possible. However,
I do wonder why you want to move attachments out of the database? You do
realize that the attachments are also deduplicated, right? Send a 1MB
attachment to a million users on your service and it will only be stored
There aren't any limitations that matter; you'll probably want to listen
for a couple of database signals. mailboxes_updated is a crock and will
sooner or later make trouble.
I think your design makes a very great deal of sense. In fact it's about
the same as what I now wish Abhijit and I had

Oh. I missed that bit.
Taking attachments out of the DB makes sense in two cases:
- the db schema is poor (not the case for aox).
- the db client library sucks.
- db backups are getting too big

They don't grow any smaller by moving half the database from
/usr/local/postgres to /usr/local/homebrew.
You can shrink the backups by deleting attachments (conditionally,
blah), or by not backing up the entire db.

The point is, you can do incremental backups easily if you store

Yes. An artifact of pg_dump (and dumpall). IMO PITR backups are a better
Sorry, Arnt, that should go to the list:

A tricky issue. How should it work when the mailbox is empty, but aox undelete
would repopulate the mailbox?
Arnt
I think 'Empty Deleted' should mean what it says.
If aox undelete can recover the data, I don't think it needs to go back
to where it was, some 'salvaged' area is fine.
