MinIO server allows to throttle incoming requests:

- limit the number of active requests allowed across the cluster
- limit the wait duration for each request in the queue

These values are enabled using server's configuration or environment variables.

## Examples

### Configuring connection limit

MINIO_ACCESSKEY_SECRETKEY_TMP="/tmp/accessKey_and_secretKey_svcacct_tmp"

# connectToMinio
# Use a check-sleep-check loop to wait for MinIO service to be available
connectToMinio() {
  SCHEME=$1
  ATTEMPTS=0 ; LIMIT=29 ; # Allow 30 attempts
  set -e ; # fail if we can't read the keys.
  ACCESS=$(cat /config/rootUser) ; SECRET=$(cat /config/rootPassword) ;
  set +e ; # The connections to minio are allowed to fail.

![quota](https://raw.githubusercontent.com/minio/minio/master/docs/bucket/quota/bucketquota.png)

Buckets can be configured to have `Hard` quota - it disallows writes to the bucket after configured quota limit is reached.

## Prerequisites

- Install MinIO - [MinIO Quickstart Guide](https://min.io/docs/minio/linux/index.html#procedure).
- [Use `mc` with MinIO Server](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart)

{{- else }}
MC="/usr/bin/mc --insecure"
{{- end }}

# connectToMinio
# Use a check-sleep-check loop to wait for MinIO service to be available
connectToMinio() {
  SCHEME=$1
  ATTEMPTS=0 ; LIMIT=29 ; # Allow 30 attempts
  set -e ; # fail if we can't read the keys.
  ACCESS=$(cat /config/rootUser) ; SECRET=$(cat /config/rootPassword) ;
  set +e ; # The connections to minio are allowed to fail.

{{- else }}
MC="/usr/bin/mc --insecure"
{{- end }}

# connectToMinio
# Use a check-sleep-check loop to wait for MinIO service to be available
connectToMinio() {
	SCHEME=$1
	ATTEMPTS=0
	LIMIT=29 # Allow 30 attempts
	set -e   # fail if we can't read the keys.
	ACCESS=$(cat /config/rootUser)
	SECRET=$(cat /config/rootPassword)
	set +e # The connections to minio are allowed to fail.

# MinIO Server Limits Per Tenant

For optimal production setup MinIO recommends Linux kernel version 4.x and later.
