Storage of cubes

Last modified by Aurelie Bertrand on 2026/09/07 09:02

By default, generated cubes are stored using the file system (FileSystem). You can choose to use an Amazon S3 or compatible storage service.

💡 When S3 storage is enabled, no cubes are created or retained on the FileSystem.

The overall operation (generation, reading, automatic cleaning via fileCleaner) is exactly the same, regardless of the mode selected.

To enable and configure S3 storage:

  1. Tick the ‘S3 storage’ box and fill in the settings below.
FieldDescription
URL

Endpoint for your storage service.

For example:
[https://s3.fr-par.scw.cloud](https://s3.fr-par.scw.cloud) or [https://s3.amazonaws.com](https://s3.amazonaws.com)).

BucketName of the main container or folder in which your files will be stored.
Region

Geographical location of the server.

For example: eu-west-3 for Paris, us-east-1, etc.

Access Key IDAPI Access Key ID, equivalent to your username.
Secret Access KeyPrivate key (Secret Access Key) used to encrypt, sign and secure your requests.
  1. The following advanced options are available:
    • Use path-style URLs (ForcePathStyle): Forces the https://endpoint/bucket address format instead of the virtual format [https://bucket.endpoint](https://bucket.endpoint).
      💡 You’ll need to tick this box in almost all cases for an unofficial or compatible S3 service
    • Enable IPv4 and IPv6 (DualStack): Allows communication with the storage using either network protocol.
    • Use chunked data transfer (ChunkedEncoding): Optimises the transfer of large files.
    • Allow access to buckets in other regions (CrossRegionAccess): Allows you to read from or write to a bucket located in a region other than the one specified.
    • Use the region defined in the ARN (UseArnRegion): Applies the region specified in the ARN rather than the one in the ‘Region’ field.
  2. Click Test to check the connection to your S3 bucket.
  3. Click Save to save the changes.
  4. âš  Restart the server so that the change in storage mode takes effect.
