Hello,<br>
<br>
long story short: if you write a db connector module then implement
srdb1 interface because most of the modules are relying on that.
srdb2 comes from ser branch, only some of the uid_* modules use it.
There are couple of goodies in srdb2, but perhaps is easier to
migrate them to srdb1 rather than migrate all the modules to srdb1.
Also, srdb1 is more reach in exported API than srdb2 (which was more
or less in early phase of development at the merge time and remained
like that).<br>
<br>
Cheers,<br>
Daniel<br>

<div>Hey Everyone!</div>
<div><br>
</div>
<div>I’m currently working on a database module and I’ve come
across some issues/confusion that I was hoping someone could
clear up for me. I’ve been looking at the existing modules and
the docs online for help but I can’t find a definitive answer
for them.</div>
<ol>
<li>I see there are 2 DB APIs (srdb1 and srdb2) and I gather
that srdb2 is the newer version? Should I aim to use srdb2
exclusively or should I also use srdb1?</li>
<li>It looks like srdb2 provides a db_uri command that can be
used to implement custom URI parsing but I can’t figure out
how to hook into it. I added it to my exported commands but
it was never called. When I looked through the code I saw the
only place that ever really uses it is db_ctx, which itself
looks to be used in the child_init of modules. I’m developing
a database module that I want to be a drop-in replacement for
others, but it needs multiple hosts specified in the
connection uri (similar to the URI example here <a
moz-do-not-send="true"
href="http://docs.mongodb.org/manual/reference/connection-string">
http://docs.mongodb.org/manual/reference/connection-string</a>/)
and I can’t figure out the best place to do it. Should I be
doing it in db_func_t.init because it has the full string
version of the uri and parse it there? Do I then have to
reimplement everything that db_do_init would be doing?</li>
<li>Do I need to implement multiple database interfaces to get
full module coverage in Kamailio? I was looking at db_berkeley
as a reference and it looks like it has the
KAMAILIO_MOD_INTERFACE as well as the SER_MOD_INTERFACE
implemented.</li>
<li>Is there a preferred way to handle the API binding (such as
db_ commands vs db_bind_api)?</li>
</ol>
<div>Thanks for any help or direction you can give me!</div>
