Hi Noah, Hope you are well?
Realistically do you think you will be able to spend some time on this or do you think I need to look at other options in the short term? I guess the primary requirements for me are being able to use these modules which require database interaction (mainly Permissions,userloc,dispatcher). I have started to work through it but I am pondering if in the short term I need to focus on a support database and look to migrate when available. Thanks!

So basically, the SQL files are generated from the XSL infrastructure in the quoted directory. This file e.g. is for postgres: https://github.com/kamailio/kamailio/blob/5.4/doc/stylesheets/dbschema/xsl/postgres.xsl<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fkamailio%2Fkamailio%2Fblob%2F5.4%2Fdoc%2Fstylesheets%2Fdbschema%2Fxsl%2Fpostgres.xsl&data=04%7C01%7C%7Cfd34312b504a4723068008d8d723ebe4%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637495896580748983%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=133XFlkVh6RSwjeJJR9rNgxJda%2BHp6kwwCiqjxEBrCc%3D&reserved=0> You basically need to copy it to a new file and adapt the types in it to the cockroachdb types. If you execute “make dbschema” in the kamailio source tree, it will generate all the SQL files. Then you could generate the appropriate SQL files also for your database and it will stay in sync after future changes. There might be also a small extension necessary in the Makefile, but we can have a look to this later on. About the questions why the SQL files are then also checked in after creation – because otherwise everybody needs to install the xstl dependencies just for installing Kamailio. About the rand()/random() topic – I did not find anything in the LCR module as well. It might be obsolete. I would consider dropping this, maybe after asking on the sr-dev list for this again.

Henning mentioned on 9/16/2020 that the .sql files are generated from XML/XLST scripts, I have found: https://github.com/kamailio/kamailio/tree/5.4/doc/stylesheets/dbschema<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fkamailio%2Fkamailio%2Ftree%2F5.4%2Fdoc%2Fstylesheets%2Fdbschema&data=04%7C01%7C%7Cfd34312b504a4723068008d8d723ebe4%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637495896580768968%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=1Oy2Tr%2B0G4vqj5hsWV6FBVJrDjomsF48hQwwtmg%2FGzY%3D&reserved=0> which was updated just 3 days ago. However, I don’t understand how this is used to generate the .sql files for Postgres. I’m also confused as to why the .sql files are checked into the repository if they’re generated? Henning, can you point me in the right direction? That being said, this is what’s changed in the branch<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fkamailio%2Fkamailio%2Fcompare%2F5.4...reperio%3Acockroachdb-compat%3Fexpand%3D1&data=04%7C01%7C%7Cfd34312b504a4723068008d8d723ebe4%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637495896580778968%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=ImCDuX5GeAQ%2B5oexw1OIRcIDgjJ4e81JazzyLL8fPoQ%3D&reserved=0>: kamdbctl.pgsql - I’ve updated the psql command for my preferences regarding output - I’ve made the function checking more verbose - I’ve added the gen_random_uuid() function (by adding pgcrypto to Postgres, it’s native in CockroachDB), this isn’t required, but we are using UUID for usrloc in production - I’ve updated the GRANT commands so they’re compatible with both Postgres and CockroachDB Some things to note: - concat() is native to CockroachDB, so the CREATE FUNCTION is only necessary for Postgres - rand() is the native function name in MySQL, but random() is the function name in Postgres and CockroachDB. This is where I’m most concerned because the file says it’s used in the lcr module, but I cannot find where it is used. Does anyone know how to ascertain this? Anyways, they’re the same function, so it’s a little silly to require a CREATE FUNCTION duplicating the exact functionality of an existing native function. The rest of the changes have to do with modifying the create statements to not use SERIAL, but use the more verbose SEQUENCE + nextval(). It’s identical in practice, so there’s 0 risk there. I think overall risk is low for the branch, as the branch only changes the utility that creates the DBs. As for production use, it’s worked great for us, there have been no issues. ~Noah On Feb 18, 2021, at 2:45 PM, Jonathan Hunter <hunter...@hotmail.com<mailto:hunter...@hotmail.com>> wrote: Hi Noah, Hope you are well? I work as a consultant for a company in the UK, and I am building a new hosted telephony platform for them in docker initially, and as we are deploying across multiple servers they want to use cockroachdb to allow easy management of a cluster environment. I could see from your posts you got it working using your own branch, and I wondered what changes you made to make things work correctly and what would be needed to get the kamailio dev’s to accept it into the main stream of code? (Happy to help here where I can). Unless you will maintain your branch forever 😊 Or are the changes small so its not too much of a concern? I just want to assess the risk really, and like you I think mainly we will just be using userloc and dispatcher for DB interaction so its positive to hear they work fine. We would also be using rtpengine, routing data will be done via API so that should be fine. FYI Id like to run kamailio 5.4 initially. I see your comments about table creation (in previous posts), that is the initial problem I am seeing when trying to use postgres based commands direct from a pgdump to create the kamailio database structure, does your branch contain all the creation scripts for the db/tables that I can use for testing?
