Looks to be a good idea.
I use MySQL and MyISAM, so I understand that async is supported.
Async
(db_insert_mode=2) is supported with any (acc)backend. With myisam you
can use delayed inserts (db_insert_mode=1). But without even looking at
the kamailio implementation I'd guess that 2 is the better choice in the
hope that the sql operation is entirely done in an other thread, with 1
there might be the chance that setting up/reusing connections might
block (since insert delayed is a feature on the mysql server side that
just returns an OK before any writes to disk).

How should I dimension the number of
async_workers?
I set it to 2, but for acc and a few async sql_ops calls that should
be
overkill. I have no metrics to make a better assumption on the number of
worker threads.
