Mongo DB connection - More connections
I use mongo DB in Atlas and have a maximum of 500 connections.
When I launch novu in production mode I always get emails from mongo warning me that the connections to my clusters have exceeded 500.
Do you have any solutions? Is this normal behaviour ?

hello @dave93.
try to tweak
MONGO_MAX_POOL_SIZE env variable
Not working, i try with 490 but receive the same emails from Atlas.
what version of Novu do you run? As I remember this variable was added quite recently
I will try to download the latest version
Thanks @madd.man

As far I know - if you just run docker compose with worker, api with

What is your cluster tier?

I noticed that
