[Asterisk-Users] Nested MySQL Commands

[Douglas Garstang]

jd.... but..... but.... Asterisk still fires up a process each time you make an AGI call in the dialplan. You could still have 120 of these lightweight processes running, in _addition_ to the other process. Doesn't sound like it provides much benefit.

Yes, but if you need it to scale efficiently, each of these could
be a very lightweight process. If you used each of these to communicate
via RPC or shared memory to a process with a small and configurable pool
of database connections (which isn't that difficult), you can build a
simple and scalable solution.
