So you are migrating from Sqlite to Postgres because you need it. What is the state of your product when you need to do this migration? Is your product non trivial? Are you now dependent on particular performance characteristics of Sqlite? Do you now need to keep your service running 24/7? Accounting for all of that takes way more than 5 minutes. The only way to beat that is if you still have a toy product and you can just export the database and import it and pray that it all works as a migration strategy.

Yes it might be risky. But most schema evolution changes can be done with no or minimal downtime even if you have to do then in multiple steps. When is a simple ALTER going to be totally unacetable if youare using Sqlite?

Do you know why it is a toy? Because in a real prod environment after inserting 240k rows per second for a while you have to deal with the fact that schema evolution is required. Good luck migrating those huge tables with Sqlite ALTER table implementation

Gets proper backups if you back it up the right way https://sqlite.org/backup.html

I bet that takes more time than the 5 extra minutes you take to setup Postgres in the same box upfront.

What do you recomend as reading material for someone that was in college a while ago (before AE modes got popular) to get up to speed with the new PQ developments?

I read the article and to be honest I don't know where we disagree. I disagree with this quote,

> Takes ~10min to revert a bad deploy

A bad deploy can take way over that just in customer or partner management communication.

> The other side of this is building safety nets. Takes ~10min to revert a bad deploy.

Does it? Reverting a bad deploy is not only about running the previous version.

Did you mess up data? Did you take actions on third party services that that need to be reverted? Did it have legal reprecursions?

I wouldn't say acceptance of crappy code. I think the issue is the acceptance of LLM plans with just a glance and the acceptance of code without any code review by the author at all because if the author would waste any more time it wouldn't be worth it anymore.

The problem is those plans become huge. Now I have to review a huge plan and the comparatively short code change.

Does that mean CXMT is one inch away from also eating into the DDR5 market?

Maybe they reverted it because they are already planning to get rid of the super rounded corners!

I would upvote this comment more if I could.

I already refrained from introducing event sourcing to tackle wierd dependecies multiple time just by justaposing the amount of discipline that the team has that lead to the current state vs the discipline that is required to keep the event source solution going.

I don't agree with this cache take. Adding operations to the cache is easy. Taking the django-redis project as an example there are only two levels until you reach redis-py: The cache abstraction and the client abstraction.

The problem with channels is that if you need to touch the ORM you will have to use a sync_to_async call which will block the event loop.

Why don't you post the original broken Python code.

Scale articles are too focused on architecture. What about business problems that come with scale. At a certain scale rare events are common many cases cease to be fixable by some random process that involves humans you have to handle a lot more business scenarios with your code.
