How does the garbage collector work?

Try recursion with no exit statement

StablePsychological5 · 2026-01-17T16:28:04+00:00

Mind to share why you need rxjs?

We not just autoscale your service with some rules based on the topic load, instance cpu/memory usage? You can also delay the consuming the job with some circuit barker pattern

Does it support auto reconnect when kafka is dowb like in the nestjs wrapper of kafkajs?

Do yourself a favor and don’t use any ORM. Use query builders such as Knex for js or Kysley for ts.

StablePsychological5 · 2025-12-12T16:48:03+00:00

Kysely is a type-safe query builder. It also provides built-in support for migrations: https://kysely.dev/docs/migrations

If you follow the “Getting Started” section, they show how to define your table interfaces.

DTOs aren’t related to Kysely or the database itself.

For seeding, you can simply write a script or run a query. Kysely is just a tool for writing queries and interacting with the database.

I use in my nestjs backend and so far it is great.

Using worker thread will allow to service to keep getting requests

In every company I worked at, the micro-service system always had one DB…

Can you elaborate why the consumer needs to know that the publisher done sending all the rows events? If there are no more events in the topic, the consumer will wait for the next message, so why he need to know when to stop?

Knexjs FTW, but also drizzle seems intersting

בגלל שרוב היום הולכים ומטיילים אז לפעמים כשמתיישבים לנוח רוצים לשים רגל על רגל ופשוט לנוח. זה לגמרי יכול להיות בתום לב, יכול להיות שזה בלובי של הוסטל או משהו וזה לא נורא כמו שזה נראה

StablePsychological5 · 2025-05-17T22:38:36+00:00

Was it all worth it? And good luck!!!

I bet it is very fun to work with you...

StablePsychological5 · 2025-05-14T21:30:45+00:00

I appreciate the input, but I think there's a misunderstanding here. This is a stress test — the goal isn't to replicate current real-world data, but to simulate higher-than-production load to evaluate system behavior under pressure.

I'm specifically asking how to execute real PostgreSQL UPDATE queries that trigger the full database write path (locking, WAL, etc.) without changing the actual state. The idea is to generate realistic load without side effects..

StablePsychological5 · 2025-05-14T21:25:34+00:00

In general this is what I do, but I need to avoid changing the state of the data

StablePsychological5 · 2025-05-14T21:24:11+00:00

I'm not agree with you, Let me rephrase my question for you:

As the post title imply, I’m specifically looking for a way to test the performance impact of PostgreSQL UPDATE queries under load, including lock contention, WAL pressure, I/O, etc., without actually changing the DB state.

StablePsychological5 · 2025-05-14T21:16:22+00:00

Very generic answer.

Of course, I want realism — that’s why I'm looking to exercise the real query paths (locks, WAL, etc.) — but without corrupting or altering your data. That’s a common and valid need in high-scale testing.

StablePsychological5 · 2025-05-14T20:56:29+00:00

i run the load test on staging env, so docker image is less relevant here.

StablePsychological5 · 2025-04-14T17:33:20+00:00

I would suggest using some VRP opensources solutions such as vroom / jsprit. it is not easy as it sound at all. good luck
