Instructions

Bucket Quota:

A quota is a limit that defines the maximum size that a certain resource (buckets or namespaces) can have. Admin users set this limit. It is set in GiBs with a minimum of 1 GB.

Two types of Quota exist: Soft Quota and Hard Quota; they only differ in the action taken when the quota is breached.

  • Hard quota: Once the limit is breached, no more writes or appends are allowed on the corresponding resource; the only action allowed is objects or buckets deletion
  • Soft quota: Only an alert is raised.

 

Note: Soft and hard quotas can only be defined at the bucket or namespace creation level.

 

To set a quota on a bucket:

  1. Create a management user and provide its name and password.

Go to Manage > Management Users > New Management User.

New management user

  1. Create a namespace:

Go to Manage > Namespace > New namespace.

Create new namespace

  1. Create a bucket:

Go to Manage > Buckets > New Bucket.
 

Note: Name the bucket and select the namespace and replication group that the bucket belongs to, and type in the bucket owner user.
 

Create new bucket

  1. Set the quota on the bucket, at creation level, using one of the below options:

  • Notification Only at <quota_limit_in_GiB> Soft quota setting at which you are notified.
  • Block Access Only at <quota_limit_in_GiB> Hard quota setting which, when reached, prevents write or update access to the bucket.
  • Block Access at <quota_limit_in_GiB> and Send Notification at <quota_limit_in_GiB> Hard quota setting which, when reached, prevents write or update access to the bucket and the quota setting at which you are notified.
