hi,
what do you think about the Dialplan module? it can probably do the trick
as well...

Hello Uri
I had similar needs and I found the ndb_redis module more suited for that
type of task. Instead of a tree you have a hash like this: tname tprefix
tvalue. If you do a hget nts $avp(DID) and you get a not null value you
have found your exact match. It works very well for me and the time it
takes for that "query" is barely noticeable. Of course redis does not
address items like persistence, etc the same way a rdbms does.
for hash tables in config, the alternative is using htable module. Then
the selection is done on exact match, no prefix matching. mtree is suitable
for storing keys that are composed from a limited set of characters (like
numbers, 0-9 digits only), otherwise becomes too memory consuming. For keys
that are composed from any character and need exact match, hash table
structures are more suitable, no matter if it is via htable module or
something else like redis.

Daniel
Hope it helps.
