Sure, you can do it that way.  However, htable and mtree accommodate relatively primitive data sets.

Given sufficient table complexity and/or size, your best bet is to use an in-memory storage backend on the database side itself.

In MySQL, this is called:

Hello,

I need to query a database for every SIP request coming into Kamailio,
but I want this to be handled as fast as possible, so I was thinking of
loading the data I need in memory using the HTABLE or MTREE modules.

When the SIP request is coming from one of our carriers, the called
number ($rU) must be used to get the data for this called number.
Normally, I would query the database, using sqlops, and pass the value
of $rU as the parameter and get the column values using the $dbr
variable. Can this be accomplished with HTABLE or MTREE?

Also, the autoexpire parameter in HTABLE; once expired, will the data be
reloaded again from the database?

Thanks,


Grant
