yes, the plan is to index in parallel using a "notification" scheme. Where
the storage layer will notify the indexer of message id's it needs to
retrieve and index, or message id's it needs to delete, these notifications
will go on a queue. The indexer will then go and get the mail messages when
it can and index or delete from the index as needed.

I guess I was just looking for some validation on the approach, and maybe
how others were working around the one writer per database "problem".

We do over 100 million delivery attempts a day, not all those would get
indexed as a little more than half is spam and never gets delivered, but you
can see I have some big numbers to deal with.
