what is ram requirements

[furllmm]

i have problem minio uses more ram overtime up to %100 ram usage uses like 3g ram
i wondered ram requirements
is there any chance for limit ram usage if possible

i have 8G ram
laptop b/m: lenovo ideapad slim 3

We have some light guidance on recommended memory based on host storage.

As of https://github.com/minio/minio/releases/tag/RELEASE.2024-01-28T22-35-53Z we pre-allocate a minimum of 2Gi per node in distributed and 1Gi per node in single-node topologies. Add set CI_CD=true envvar to reduce this allocation to 256MiB. Persisting this value across restarts will depend on your operating system.

You could always run MinIO in a container and limit memory that way.

podman run -dt                                  \
  -p 9000:9000 -p 9001:9001                     \
  -v PATH:/mnt/data                             \
  -v /etc/default/minio:/etc/config.env         \
  -memory "2Gi"                                 \
  --name "minio_local"                          \
  minio server --console-address ":9001"

Set all environment variables in the /etc/default/minio file, or whatever path to an envar file you want for your local system.

What does set CI=true mean?

[wuyudian1]

In the source code, we can find the answer:
./cmd/erasure-server-pool.go

	if globalIsCICD || strconv.IntSize == 32 {
		n = 256 // 256MiB for CI/CD environments is sufficient or on 32bit platforms.
	}

[xujuchao]

Does that mean 64-bit platforms don't need to be set up?

[wuyudian1]

这个和系统是多少位的没关系，源码注释中用的是 or，表示2中条件中的任何一种满足，都会设置n = 256。
如果你不想预先分配那么大的内存，不用管到底是32位系统还是64位系统，你直接设置 CI = true，就能确保 n = 256

明白了谢谢 @wuyudian1
