Loading data from Yandex Managed Service for OpenSearch to Yandex Object Storage using Yandex Data Transfer

With Data Transfer, you can transfer data from a Managed Service for OpenSearch cluster to Object Storage.

To transfer data:

1. Prepare the test data.
2. Prepare and activate the transfer.
3. Test the transfer.

If you no longer need the resources you created, delete them.

Getting startedGetting started

Prepare the infrastructure:

Prepare the test dataPrepare the test data

1. Connect to the Managed Service for OpenSearch source cluster.

2. Create a test index named people and set its schema:

   curl --user admin:<password> \
        --cacert ~/.opensearch/root.crt \
        --header 'Content-Type: application/json' \
        --request PUT 'https://<address_of_OpenSearch_host_with_DATA_role>:9200/people' && \
   curl --user admin:<password> \
        --cacert ~/.opensearch/root.crt \
        --header 'Content-Type: application/json' \
        --request PUT 'https://<address_of_OpenSearch_host_with_DATA_role>:9200/people/_mapping?pretty' \
        --data'
        {
              "properties": {
                 "name": {"type": "text"},
                 "age": {"type": "integer"}
              }
        }
        '
   

3. Populate the test index with data:

   curl --user admin:<password> \
        --cacert ~/.opensearch/root.crt \
        --header 'Content-Type: application/json' \
        --request POST 'https://<address_of_OpenSearch_host_with_DATA_role>:9200/people/_doc/?pretty' \
        --data'
        {
              "name" : "Alice",
              "age" : "30"
        }
        ' && \
   curl --user admin:<password> \
        --cacert ~/.opensearch/root.crt \
        --header 'Content-Type: application/json' \
        --request POST 'https://<address_of_OpenSearch_host_with_DATA_role>:9200/people/_doc/?pretty' \
        --data'
        {
              "name" : "Robert",
              "age" : "32"
        }
        '
   

4. (Optional) Check the data in the test index:

   curl --user admin:<password> \
        --cacert ~/.opensearch/root.crt \
        --header 'Content-Type: application/json' \
        --request GET 'https://<address_of_OpenSearch_host_with_DATA_role>:9200/people/_search?pretty'
   

Prepare and activate the transferPrepare and activate the transfer

1. Create a target endpoint of the Object Storage type with the following settings:

   • Bucket: <name_of_previously_created_bucket>.
   • Service account: <name_of_previously_created_service_account>.
   • Serialization format: JSON.
   • Encoding format: [object Object].
   • Folder name: from_MOS.

2. Create a source endpoint of the OpenSearch type with the following settings:

   • Connection type: Managed Service for OpenSearch cluster.
   • Managed Service for OpenSearch cluster: Select a Managed Service for OpenSearch cluster from the list.
   • User: admin.
   • Password: <user_password>.

3. Create a transfer:

   Manually

   Terraform

   1. Create a transfer of the Snapshot type that will use the created endpoints.

   2. Activate the transfer.

   1. In the opensearch-to-object-storage.tf file, specify the values of the following variables:

      • target_endpoint_id: ID of the target endpoint.
      • source_endpoint_id: ID of the source endpoint.
      • transfer_enabled: Put 1 to create a transfer.

   2. Check that the Terraform configuration files are correct using this command:

      terraform validate
      

      If there are any errors in the configuration files, Terraform will point them out.

   3. Create the required infrastructure:

      1. Run the command to view planned changes:

         terraform plan
         

         If the resource configuration descriptions are correct, the terminal will display a list of the resources to modify and their parameters. This is a test step. No resources are updated.

      2. If you are happy with the planned changes, apply them:

         1. Run the command:

            terraform apply
            

         2. Confirm the update of resources.

         3. Wait for the operation to complete.

      Once created, your transfer will be activated automatically.

Test the transferTest the transfer

Make sure the data has been transferred from the Managed Service for OpenSearch cluster to the Object Storage bucket:

1. Wait for the transfer status to change to Completed.
2. In the management console, select the folder where the bucket is located.
3. In the list of services, select Object Storage.
4. Select the bucket from the list.
5. Go to the Objects tab.
6. Check that the Object Storage bucket contains the from_MOS folder with the JSON file with the test data.

Delete the resources you createdDelete the resources you created

Some resources are not free of charge. To avoid paying for them, delete the resources you no longer need:

1. Delete the transfer.
2. Delete the endpoints.
3. Delete the from_MOS folder from the created bucket.

Delete the other resources depending on how they were created:
