Increasing the timeout, pool size and pooling in the connection string helped in my case. — I faced the same issue where the first connection attempt or a connection after a longer period would immediately time out. Outcome: I added these parameters: `Timeout=60;Command Timeout=60;Pooling=true;MinPoolSize=1;MaxPoolSize=200`.

REQUIRESSolution

just don't do it. — while still being able to show an accurate unread counter. Tension: avoid updating many rows on every new message. Outcome: Save a bookmark where they left off and count whatever appeared after that.

REQUIRESSolution

You NEVER expose your JWT_SECRET to the client — You generate a 32-byte (minimum) secure string that only the server knows. Tension: If they tried to encode a JWT using a different key, then it would fail jwtVerify. Outcome: a user cannot forge a token because they don't know the key.

REQUIRESSolution

In addition to the suggestion of using a Lua script, you could stick to your solution of using `INCR` — since redis is single threaded so this will be thread safe. Tension: how to reset this key when value reaches to 25k in a thread safe way. Outcome: simulate the reset of the counter on the client side by taking the remainder of the returned value.

REQUIRESSolution

Separate the Django web server and Celery worker into different containers or services

PERTAIN_TOProblem

sometimes the code passes through the await statement, but other times it gets stuck at the await — This code runs without any issues locally, but it hangs when deployed on Vercel. Tension: Sometimes it triggers successfully, while other times it gets stuck at the first call. Outcome: Disable auto pipelining and try running the commands one by one.

PERTAIN_TOProblem

sentry-sdk sends every raised CustomError to the DSN

PERTAIN_TOProblem

Multiple threads are writing in the file concurrently. — I need to persist this counter because if process get restarted then it counter should start from last count. Tension: I hope there wont be a case when any number shall be skipped or give duplicate value to thread. Outcome: how to reset this key when value reaches to 25k in a thread safe way.

PERTAIN_TOProblem

Could not find backend 'django.core.cache.backends.redis.RedisCache': No module named 'django.core.cache.backends.redis' — I want to use Redis through docker for the cache. Tension: My cache settings are this.

INVOLVESProblem

Error -2 connecting to redistester:6380. Name or service not known.

This optimises the app for inactive (non-)users — for unread messages, every time someone sends a message in a chat. Tension: it should stay out of the way of active users' traffic. Outcome: you want the opposite.

AFFECTSRootCause

it could be because the sdk is getting an error and appear to be hanging while it's retrying — Disable retry. Tension: the sdk is getting an error and appear to be hanging while it's retrying. Outcome: Disable retry. If the issue persists, it could be because the sdk is getting an error and appear to be hanging while it's retrying.

AFFECTSRootCause

init() is configured without a filter, so every captured exception event is sent

AFFECTSRootCause

Seems like vanilla case of deadlock, the asyncio only lock the same process. — To avoid race conditions, I added an asyncio.Lock() around Redis writes. Tension: it didn’t help. Outcome: You can use redis lock to solve this.

AFFECTSRootCause

Tension: My question is: Does `SessionMiddleware` store the session data in the cookie on the client or does it just encode an ID and the session data is saved on the server? Outcome: If needed, you can store session data on server-side and only keep an ID in the cookie.

AFFECTSRootCause

The token is visible in inspect > application tab in my browser. — The frontend stores the token in localStorage. Tension: it is saved in the client's device (in this case, the browser), and no one else can access that storage. Outcome: storing the access token in the local storage.

AFFECTSRootCause

Outcome: Running inside container on self-hosted.

AFFECTSRootCause

The result is still too long — for example, around 13,000+ characters with Base64URL-encoded Deflate — encoded structure (like a hash or serialized data). Outcome: Hashes are not reversible. They do allow collisions.

AFFECTSRootCause

how to reset this key when value reaches to 25k in a thread safe way. — Multiple threads are writing in the file concurrently. Tension: any number shall be skipped or give duplicate value to thread.

Tension: I hope there wont be a case when any number shall be skipped or give duplicate value to thread. Outcome: how to reset this key when value reaches to 25k in a thread safe way.

AFFECTSRootCause

MySiteName is a folder that also contains settings.py and celery.py. Outcome: from .celery import app as celery_app.

AFFECTSRootCause

app = Celery('projectSlackBot'). Tension: it did not work completely for me.

AFFECTSRootCause

python manage.py migrate, celery -A api worker -l INFO --detach, and python manage.py runserver cannot all be treated as one entrypoint process

AFFECTSRootCause

Django introduced the Redis backend in version 4.0. — in the docker container. Tension: Make sure the the Django version in the docker container is at least 4.0. Outcome: Django introduced the Redis backend in version 4.0.

AFFECTSProblem

Could not find backend 'django.core.cache.backends.redis.RedisCache': No module named 'django.core.cache.backends.redis' — I want to use Redis through docker for the cache. Tension: My cache settings are this.

AFFECTSRootCause

connections are sometimes not closed at all. Tension: We were using Django 3.2 and before the update everything was fine. Outcome: Only happens to us in production.

AFFECTSRootCause

Tension: this will only limit this at.

AFFECTSProblem

CSS assets are not loading in Django running in Docker
