This mode ensures that all SIP registrations are
directly written to the
'location' mysql table, without being buffered in a memory cache. Since
mysql cluster uses in-memory databases, performance is pretty good even
with db_mode 3, at least if you run a cluster data node on the same host
as openser.
some of the presence stuff does not work with db_mode=3. what is the
disadvantage of using mode 1 or 2 in the proxy that receives register
request from user and 0 in others?
