Use Import Resource	Learn how to manage the import task using the import resource.

Use Import Resource

You can learn how to import data to a TiDB Cloud cluster with the tidbcloud_import resource in this document.

The features of the tidbcloud_import resource include the following:

Create import tasks for TiDB Cloud Serverless and TiDB Cloud Dedicated clusters.
Import data either from local disks or from Amazon S3 buckets.
Cancel ongoing import tasks.

Prerequisites

Get TiDB Cloud Terraform Provider.
Create a TiDB Cloud Serverless cluster or Create a TiDB Cloud Dedicated cluster.

Create and run an import task

You can manage either a local import task or an Amazon S3 import task using the import resource.

Create and run a local import task

Note:

Importing local files is supported only for TiDB Cloud Serverless clusters, not for TiDB Cloud Dedicated clusters.

Create a CSV file for import. For example:
```
id;name;age
1;Alice;20
2;Bob;30
```

Create an import directory, and then create a main.tf inside it. For example:

terraform {
 required_providers {
   tidbcloud = {
     source = "tidbcloud/tidbcloud"
   }
 }
}

provider "tidbcloud" {
  public_key = "your_public_key"
  private_key = "your_private_key"
}

resource "tidbcloud_import" "example_local" {
  project_id  = "your_project_id"
  cluster_id  = "your_cluster_id"
  type        = "LOCAL"
  data_format = "CSV"
  csv_format = {
    separator = ";"
  }
  target_table = {
    database = "test"
    table  = "import_test"
  }
  file_name = "your_csv_path"
}

Replace resource values (such as project ID, cluster ID, and CSV path) in the file with your own. And you can find details of csv_format on the configuration page.

Run the terraform apply command to create an import task, and then type yes to confirm the creation and start the import:

$ terraform apply
...
Plan: 1 to add, 0 to change, 0 to destroy.

Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.

Enter a value: yes

tidbcloud_import.example_local: Creating...
tidbcloud_import.example_local: Creation complete after 6s [id=781074]

Use terraform state show tidbcloud_import.${resource-name} to check the status of the import task:

$ terraform state show tidbcloud_import.example_local
# tidbcloud_import.example_local:
resource "tidbcloud_import" "example_local" {
    all_completed_tables          = [
        {
            message    = ""
            result     = "SUCCESS"
            table_name = "`test`.`import_test`"
        },
    ]
    cluster_id                    = "1379661944641274168"
    completed_percent             = 100
    completed_tables              = 1
    created_at                    = "2023-02-06T05:39:46.000Z"
    csv_format                    = {
        separator = ";"
    }
    data_format                   = "CSV"
    elapsed_time_seconds          = 48
    file_name                     = "./t.csv"
    id                            = "781074"
    new_file_name                 = "2023-02-06T05:39:42Z-t.csv"
    pending_tables                = 0
    post_import_completed_percent = 100
    processed_source_data_size    = "31"
    project_id                    = "1372813089191151295"
    status                        = "IMPORTING"
    target_table                  = {
        database = "test"
        table  = "import_test"
    }
    total_files                   = 0
    total_size                    = "31"
    total_tables_count            = 1
    type                          = "LOCAL"
}

Use terraform refresh to update the status after several minutes:

$ terraform refresh && terraform state show tidbcloud_import.example_local
tidbcloud_import.example_local: Refreshing state... [id=781074]
# tidbcloud_import.example_local:
resource "tidbcloud_import" "example_local" {
    all_completed_tables          = [
        {
            message    = ""
            result     = "SUCCESS"
            table_name = "`test`.`import_test`"
        },
    ]
    cluster_id                    = "1379661944641274168"
    completed_percent             = 100
    completed_tables              = 1
    created_at                    = "2023-02-06T05:39:46.000Z"
    csv_format                    = {
        separator = ";"
    }
    data_format                   = "CSV"
    elapsed_time_seconds          = 49
    file_name                     = "./t.csv"
    id                            = "781074"
    new_file_name                 = "2023-02-06T05:39:42Z-t.csv"
    pending_tables                = 0
    post_import_completed_percent = 100
    processed_source_data_size    = "31"
    project_id                    = "1372813089191151295"
    status                        = "COMPLETED"
    target_table                  = {
        database = "test"
        table  = "import_test"
    }
    total_files                   = 0
    total_size                    = "31"
    total_tables_count            = 1
    type                          = "LOCAL"
}

When the status turns to COMPLETED, it indicates that the import task is finished.

Check the imported data with MySQL CLI:

mysql> SELECT * FROM test.import_test;
+------+-------+------+
| id   | name  | age  |
+------+-------+------+
|    1 | Alice |   20 |
|    2 | Bob   |   30 |
+------+-------+------+
2 rows in set (0.24 sec)

Create and run an Amazon S3 import task

Note:

To allow TiDB Cloud to access your files in the Amazon S3 bucket, you need to configure Amazon S3 access first.

Create an import directory, and then create a main.tf inside it. For example:

terraform {
  required_providers {
    tidbcloud = {
      source = "tidbcloud/tidbcloud"
    }
  }
}

provider "tidbcloud" {
  public_key  = "your_public_key"
  private_key = "your_private_key"
}

resource "tidbcloud_import" "example_s3_csv" {
  project_id   = "your_project_id"
  cluster_id   = "your_cluster_id"
  type         = "S3"
  data_format  = "CSV"
  aws_role_arn = "your_arn"
  source_url   = "your_url"
}

resource "tidbcloud_import" "example_s3_parquet" {
  project_id   = "your_project_id"
  cluster_id   = "your_cluster_id"
  type         = "S3"
  data_format  = "Parquet"
  aws_role_arn = "your_arn"
  source_url   = "your_url"
}

Run the terraform apply command to create an import task, and then type yes to confirm the creation and start the import:

$ terraform apply
...
Plan: 2 to add, 0 to change, 0 to destroy.

Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.

Enter a value: yes

tidbcloud_import.example_s3_csv: Creating...
tidbcloud_import.example_s3_csv: Creation complete after 3s [id=781075]
tidbcloud_import.example_s3_parquet: Creating...
tidbcloud_import.example_s3_parquet: Creation complete after 4s [id=781076]

Use terraform refresh and terraform state show tidbcloud_import.${resource-name} to update and check the status of the import task.

Update an import task

Import tasks cannot be updated.

Delete an import task

For Terraform, deleting an import task means canceling the corresponding import resource.

You cannot cancel a COMPLETED import task. Otherwise, you will get a Delete Error as in the following example:

$ terraform destroy
...
Plan: 0 to add, 0 to change, 1 to destroy.

Do you really want to destroy all resources?
  Terraform will destroy all your managed infrastructure, as shown above.
  There is no undo. Only 'yes' will be accepted to confirm.

  Enter a value: yes

tidbcloud_import.example_local: Destroying... [id=781074]
╷
│ Error: Delete Error
│
│ Unable to call CancelImport, got error: [DELETE /api/internal/projects/{project_id}/clusters/{cluster_id}/imports/{id}][500] CancelImport default  &{Code:59900104 Details:[] Message:failed to cancel
│ import}
╵

You can cancel an import task whose status is IMPORTING. For example:

$ terraform destroy
...
Plan: 0 to add, 0 to change, 1 to destroy.

Do you really want to destroy all resources?
  Terraform will destroy all your managed infrastructure, as shown above.
  There is no undo. Only 'yes' will be accepted to confirm.

  Enter a value: yes

tidbcloud_import.example_local: Destroying... [id=781074]
tidbcloud_import.example_local: Destruction complete after 0s

Destroy complete! Resources: 1 destroyed.
