bytebase VS walex

We have been building https://github.com/bytebase/bytebase for 3+ years. You can think it of as GitHub/GitLab for SQL changes, with integrated GitOps, code review and deployment.

You can further check out this tutorial to get a feel of our GitOps solution

We have been working on bytebase (https://github.com/bytebase/bytebase) for 3+ years to address this. With a change review workflow, environment propagations, and try not to disturb the dev flow if possible.

Migrations. All my database logic lives in version control.

Popular tooling like Phoenix, Hasura, etc have good built in migration stories.

https://www.bytebase.com looks really promising.

Hover, I do struggle with one big issue: changing database logic (views, functions, etc) that has other logic dependent on it. This seems like a solvable problem.

Bytebase offers a powerful GUI for schema migration deployments. This tutorial will show you how to use Bytebase to deploy schema migrations with features like SQL Review, custom approval, time scheduling, and more.

Now there are more subdivided practice: * Policy as Code: Sentinel, OPA * Database as Code: bytebase * AppConfiguration as Code: KusionStack, Acorn * ...... (Welcome to add more)

Bytebase is an open-source Database DevOps and CI/CD tool for teams, designed to centralize the control and secure your organization’s most valuable asset, the database data.

I use Bytebase to manage database changes for MySQL with GitOps workflow. I can manage my SQL scripts in my GitLab repo, and trigger a database change issue with committing a MR. Then Bytebase will record it after the issue is executed successfully. But I am not sure whether it supports procedures. Refer to https://github.com/bytebase/bytebase to get more details.

The WAL CDC approach: https://github.com/cpursley/walex?tab=readme-ov-file#publica...

CREATE PUBLICATION news_item FOR TABLE news WHERE (topic IS "AAPL");

What do you mean testing with processes?

I won't suggest these are the best written tests, but I test various processes, supervisors, etc like this:

https://github.com/cpursley/walex/blob/master/test/walex/sup...

You don’t send the entire WAL, just what you subscribe to - and you can even filter via SQL: https://github.com/cpursley/walex?tab=readme-ov-file#publica...

What we do is much if the business logic in Postgres. But then there’s all the other stuff like external integrations, etc.

We handled that by having an Even system built on the Postgres WAL that we use like a callback system.

I put together a little library in Elixir (that originally started out as forked Supabase realtime) for this:

https://github.com/cpursley/walex

Recently added the ability to configure WalEx to forward events to webhooks or EventRelay (so you don’t need to know Elixir).

If you're using Elixir, check out https://github.com/cpursley/walex

I've actually been thinking about turning this idea into a product where you can just point it at your postgres database and select the tables you want to listen to (with filters, like you describe). And have that forwarded to a webhook (with possibility of other protocols).

I'd love to hear folks thoughts on that (and if it would be something people would pay for).

Neat, this is the pattern I've been thinking about for a while now. Also glad to see this is Elixir based.

I've been using https://github.com/cpursley/walex (basically a fork of cainophile via a fork for subabase) to listen to Postgres changes in Elixir.

https://github.com/cpursley/walex

Which is based on WAL logs and doesnt have the same limitations.

Great writeup, just added this to the WalEx readme:

https://github.com/cpursley/walex

(WalEx is an Elixir lib for listening to the WAL and perform callback-like actions with the data)

Very cool.

I'm using Elixir to listen to change events via https://github.com/cpursley/walex (which I basically ripped off from Supabase).
