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 your transfer.
3. Test the transfer.

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

Required paid resourcesRequired paid resources

The support cost includes:

• Managed Service for OpenSearch cluster fee: Using computing resources allocated to hosts (including hosts with the MANAGER role) and disk space (see Managed Service for OpenSearch pricing).
• Fee for using public IP addresses for cluster hosts (see Virtual Private Cloud pricing).
• Object Storage bucket fee: Storing data and performing operations with it (see Object Storage pricing).
• Per-transfer fee: Using computing resources and the number of transferred data rows (see Data Transfer pricing).

Getting startedGetting started

Set up your infrastructure:

Prepare the test dataPrepare the test data

1. Connect to the source Managed Service for OpenSearch 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. Optionally, 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 your transferPrepare and activate your 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: 1 to create a transfer.

   2. Make sure 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 this command to view the planned changes:

         terraform plan
         

         If you described the configuration correctly, the terminal will display a list of the resources to update and their parameters. This is a verification step that does not apply changes to your resources.

      2. If everything looks correct, apply the changes:

         1. Run this command:

            terraform apply
            

         2. Confirm updating the 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. From the list of services, select Object Storage.
4. Select the bucket from the list.
5. Navigate to the Objects tab.
6. Make sure the Object Storage bucket contains the from_MOS folder with the test data JSON file.

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 bucket you created.

Delete the other resources depending on how they were created:
