FAQ about projects

Causes

A project cannot be deleted if either of the following conditions exists:

• The project still has an Object Storage Service (OSS) bucket binding.

• The project still has a dataset.

Solution

To delete a project, remove all associated resources in the following order. The diagram below shows the resource dependency chain:

Project
  |-- OSS Bucket Binding  --> DetachOSSBucket (remove first)
  |-- Dataset
       |-- File Metadata   --> DeleteFileMeta / BatchDeleteFileMeta (remove first)
       (empty dataset)     --> DeleteDataset (remove second)
  (empty project)          --> DeleteProject (remove last)

Follow these steps:

1. Check whether the project is bound to an OSS bucket.

   • If yes, call the DetachOSSBucket operation to unbind the bucket from the project, and then proceed to Step 2.

   • If no, proceed to Step 2.

2. Check whether a dataset exists in the project.

   • If yes, proceed to Step 3.

   • If no, proceed to Step 5.

3. Check whether the dataset contains metadata.

   • If yes, delete the metadata from the dataset by using the IMM console, the DeleteFileMeta operation, or the BatchDeleteFileMeta operation.

   • If no, proceed to Step 4.

4. Delete the dataset by using the IMM console or the DeleteDataset operation.

5. Delete the project by using the IMM console or the DeleteProject operation.
