Alex, we're primarily using MSSQL as our database server and would like to keep it that way. But since Gary has accomplished this with MTREE, I'll give that a go. 7 million records is very impressive. Our tables won't have near that much records, just a few hundred.
I'd like to reload the data every x interval, but I don't see the MTREE having support for this, except a MI command mt_reload. I can't call this from within the configuration script right? If not, how does the TIMER module work? Does it run independently from requests, and gets triggered every set interval?

It never expire. I had loaded about 7 millions records in mtree table and there is no performance issue at all.

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.

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?
