Cubejs server is not releasing memory

[ifokeev]

Describe the bug Cubejs is not releasing the memory because of some internal cache mechanics. I tried local/redis queues and it's pretty the same. Redis is not releasing the memory too (I gave cubejs own Redis server).

To Reproduce Query the data all the time and work with cubejs quering big datasets (50K+ rows)

Expected behavior I'm expecting releasing of the memory after the query/data expired

Version: 0.26.60

Hi @ifokeev :wave:

Could you try updating to the latest version (v0.27.46 at time of writing)? Thanks in advance 😀

Hi, any update for this?

I am using 0.29.37, but memory still not release.

👋 a quick reminder that we will be replacing Redis with Cube Store as announced in this blog post.

Is it solved when we set the Cube to use the Cube Store? During my tests I can see that the memory still increasing over time even if I set Cube to work with Cube Store and an external Redis.

@guangzh3n @hiratab By default Node.js won't be releasing most of RSS memory back to the operating system once allocated. So it'd usually be normal behavior. Are you experiencing any OOM because of that? If so, please feel free to reproduce it in Cube Cloud https://cubecloud.dev/auth/signup. This will allow our engineering team to snapshot Cube memory in an environment precisely tweaked for production usage to see if there're memory leaks.
