Is there any plan for DBOS Cloud to be open-sourced?thanks

Hello @haowaiwai. We have no current plans to open-source Cloud but we would like to know - if it were - what would you do with it? Maybe there are missing pieces we can help with?

In case you haven't seen, we do have a DBOS self-hosting guide here: https://docs.dbos.dev/typescript/tutorials/self-hosting
You can use these instructions to host DBOS apps in your environment quite easily. Let us know how it goes and if you need help.

hi，We would like to run the DBOS app on a distributed database, and according to the description, DBOS supports this.

Ah, interesting! Curious to hear more.

Note that you can also "Bring your Own Database" to DBOS Cloud as long as your database is Postgres-compatible. See https://docs.dbos.dev/cloud-tutorials/byod-management

[haowaiwai]

What we are looking for is a private deployment, rather than relying on DBOS Cloud as an intermediary, so we are particularly concerned about whether DBOS Cloud will be open-sourced.

For local run (dbos start), does it support linking with PostgreSQL-compatible databases, such as Greenplum or Cloudberry?

[haowaiwai]

I tested with Greenplum and encountered the following error:

dbos migrate
Starting schema migration for database chatbot
DBOS system schema migration failed: (psycopg.errors.UndefinedFile) could not open extension control file "/usr/local/greenplum-db-6.19.2/share/postgresql/extension/uuid-ossp.control": No such file or directory

(Background on this error at: https://sqlalche.me/e/20/e3q8)

Hi @haowaiwai alas, in this case Greenplum is not "close enough" to Postgres. The "uuid-ossp" extension is something we use for UUID fields. This issue aside, an analytic database like Greenplum may not be best fit for DBOS. Regular Postgres can process a lot more write transactions per second and that comes in handy when running durable DBOS apps.

[haowaiwai]

Could you share the architecture of DBOS Cloud?

We have a blog post about it here: https://www.dbos.dev/blog/anatomy-of-dbos-cloud

Happy to answer questions about it!

[haowaiwai]

thanks

I still have a few questions:

1. DBOS centralizes applications and data, but how can it achieve data vectorization and feature extraction? Additionally, what is the goal of DBOS?
2. Is the metadata in DBOS Cloud centrally managed, making it a distributed database?
   Thank you
