<div dir="ltr"><div>Greetings,</div><div><br>I'm trying to migrate an opensips 1.7 install to 1.9. In the process, I noticed the drouting tables have changed a good bit.</div><div><br></div>After the schema was changed in 1.8 for the drouting module, this is a description of the new dr_gateways table (at the bottom).<div>
<br>My question is: there is now a "id" column, which is what i'd expect, and a gwid column, which is a varchar type that's not a sequence, not unique, but cannot be null. What is this column used for?<br>
<br>I noticed opensips 1.7, there is just a gwid column, which is an int with a sequence, which is what I expected. Is this just a way to carry that over with a db migration to 1.8 without having collisions on the sequence? So that new id's are generated, leaving this column essentially deprecated?<br>
<br>If so, why make it not null?<br><div><div><br></div><div><div>opensips=# \d dr_gateways;</div><div> Table "public.dr_gateways"</div><div> Column | Type | Modifiers </div>
