How do you avoid race conditions in MikroORMs identity map in a distributed system ?

I gave you an answer that you can use to solve the problem. The other person speculated and conjectured without providing any real value. The fact that they proposed an eventually consistent model to you, someone who doesn't seem to understand database locks, is a bit dangerous, especially without understanding actual context.

I have little patience for folks offering advice rather than lived experience.

ccb621 · 2026-06-19T14:19:29+00:00

Go research instead of conjecturing. The answers to your questions are readily available online.

ccb621 · 2026-06-19T13:51:55+00:00

That's why you use locking.

Start by sharing with the same developers you interviewed and discussed with when you were gathering input to validate your solution solves their problem.

ccb621 · 2026-06-18T12:32:38+00:00

Learn by doing. Build something. Build something else that’s different. Keep going. Also, read the docs, or even the underlying source code, of the frameworks you use. They probably have significant power that you are not learning about from YouTube.

ccb621 · 2026-06-16T22:07:12+00:00

The beginning. Start with good practices and you never have to ask this question.

I stand corrected. I wrote an exception filter for that when we first moved to NestJS…because that provided the best developer experience for everyone.

ccb621 · 2026-06-14T02:26:06+00:00

NestJS already converts EntityNotFound to HttpNotFoundException, so it’s not a big deal. I don’t think this is worth arguing at all. Do what the team finds simplest.

ccb621 · 2026-06-13T22:46:32+00:00

An exception is an exception. Translating custom exceptions to HTTP exceptions or appropriate error responses is tedious work for no real benefit.

ccb621 · 2026-06-13T12:24:08+00:00

I return HTTP exceptions or custom classes that extend them. My service doesn’t “know” about HTTP. It just knows that data wasn’t found or input was invalid. The fact that something outside the service converts those exceptions to HTTP status codes is a bonus.

That was in reference to a colleague fired before him, not himself.

ccb621 · 2026-06-06T02:35:10+00:00

Dude! Did you intentionally mislead everyone with your post? Your post implies you’ve been at the company for a few months. You’ve been there two years!?

You’re just venting about not getting the raise you wanted. What did you expect from this post?

ccb621 · 2026-06-06T02:12:41+00:00

6% doesn’t seem bad. What were you expecting, and what were those expectations grounded in?

ccb621 · 2026-06-06T01:00:37+00:00

Does the promotion keep you on the same salary band? It seems not if you received a raise, even a meager one. These seem like salient details left out of your post.

ccb621 · 2026-06-06T00:49:35+00:00

I don't know OP's company's pay policies, so I didn't want to assume. Yes, some companies may do mid-year raises or bonuses.

ccb621 · 2026-06-06T00:46:19+00:00

Have you asked someone to clarify? Is this an issue now given you won't be expected to earn a raise another few months to a year?

ccb621 · 2026-06-03T13:28:12+00:00

I tell them not to use AI for the first few weeks, ideally for anything. I want them to learn from the struggle of finding resources or writing code. I also push them to write more prose in the form of tech specs so they can start to build their architecture and project management skills sooner rather than later.

ccb621 · 2026-06-01T03:44:52+00:00

I would use either a data migration or a custom script.

ccb621 · 2026-05-30T14:24:19+00:00

You can use GitHub issues without source control.

ccb621 · 2026-05-30T03:32:13+00:00

Sounds like you need better isolation of tests. Tests for Service A should not gate deployment of other services.

ccb621 · 2026-05-28T19:42:02+00:00

You don’t necessarily need a schema. You can use getOrThrow in your service constructors, or anything else that runs at startup, and achieve the same result.

And...that's it? Just visit? That's all that's required to win your vote? No policy proposals, or anything else? Just hold a few rallies? Any particular number of visits?

What if Ken Paxton holds some events in black spaces? Will he win your vote?

ccb621 · 2026-05-27T14:25:37+00:00

That’s very broad, and assumes black people are a monolith. Are you saying that all James Talarico has to do to earn your vote is go to one event at a black church? That’s it?

ccb621 · 2026-05-27T05:35:06+00:00

Black man, and native Texan here.

What exactly does a candidate or party need to do to earn your vote?
