    Use Amazon OpenSearch Ingestion emigrate to Amazon OpenSearch Serverless


    Amazon OpenSearch Serverless is an on-demand auto scaling configuration for Amazon OpenSearch Service. Since its launch, the curiosity for OpenSearch Serverless had been steadily rising. Clients favor to let the service handle its capability routinely quite than having to manually provision capability. Till now, clients have needed to depend on utilizing customized code or third-party options to maneuver the information between provisioned OpenSearch Service domains and OpenSearch Serverless.

    We not too long ago launched a function with Amazon OpenSearch Ingestion (OSI) to make this migration much more easy. OSI is a completely managed, serverless knowledge collector that delivers real-time log, metric, and hint knowledge to OpenSearch Service domains and OpenSearch Serverless collections.

    On this publish, we define the steps to make migrate the information between provisioned OpenSearch Service domains and OpenSearch Serverless. Migration of metadata resembling safety roles and dashboard objects shall be coated in one other subsequent publish.

    Answer overview

    The next diagram exhibits the required elements for shifting knowledge between OpenSearch Service provisioned domains and OpenSearch Serverless utilizing OSI. You’ll use OSI with OpenSearch Service as supply and an OpenSearch Serverless assortment as sink.

    Conditions

    Earlier than getting began, full the next steps to create the required sources:

    1. Create an AWS Id and Entry Administration (IAM) function that the OpenSearch Ingestion pipeline will assume to jot down to the OpenSearch Serverless assortment. This function must be specified within the sts_role_arn parameter of the pipeline configuration.
    2. Connect a permissions coverage to the function to permit it to learn knowledge from the OpenSearch Service area. The next is a pattern coverage with least privileges: 
      
   "Model":"2012-10-17",
   "Assertion":[
      
         "Effect":"Allow",
         "Action":"es:ESHttpGet",
         "Resource":[
            "arn:aws:es:us-east-1:account-id:domain/domain-name/",
            "arn:aws:es:us-east-1:account-id:domain/domain-name/_cat/indices",
            "arn:aws:es:us-east-1:account-id:domain/domain-name/_search",
            "arn:aws:es:us-east-1:account-id:domain/domain-name/_search/scroll",
            "arn:aws:es:us-east-1:account-id:domain/domain-name/*/_search"
         ]
      ,
      
         "Impact":"Enable",
         "Motion":"es:ESHttpPost",
         "Useful resource":[
            "arn:aws:es:us-east-1:account-id:domain/domain-name/*/_search/point_in_time",
            "arn:aws:es:us-east-1:account-id:domain/domain-name/*/_search/scroll"
         ]
      ,
      
         "Impact":"Enable",
         "Motion":"es:ESHttpDelete",
         "Useful resource":[
            "arn:aws:es:us-east-1:account-id:domain/domain-name/_search/point_in_time",
            "arn:aws:es:us-east-1:account-id:domain/domain-name/_search/scroll"
         ]
      
   ]

    3. Connect a permissions coverage to the function to permit it to ship knowledge to the gathering. The next is a pattern coverage with least privileges: 
      {
  "Model": "2012-10-17",
  "Assertion": [
    
      "Action": [
        "aoss:BatchGetCollection",
        "aoss:APIAccessAll"
      ],
      "Impact": "Enable",
      "Useful resource": "arn:aws:aoss:area:your-account-id:assortment/collection-id"
    ,
    
      "Motion": [
        "aoss:CreateSecurityPolicy",
        "aoss:GetSecurityPolicy",
        "aoss:UpdateSecurityPolicy"
      ],
      "Impact": "Enable",
      "Useful resource": "*",
      "Situation": 
        "StringEquals": 
          "aoss:assortment": "collection-name"
        
      
    
  ]
}

    4. Configure the function to imagine the belief relationship, as follows: 
      
        "Model": "2012-10-17",
        "Assertion": [
            
                "Effect": "Allow",
                "Principal": 
                    "Service": "osis-pipelines.amazonaws.com"
                ,
                "Action": "sts:AssumeRole"
            
        ]

    5. It’s really helpful so as to add the aws:SourceAccount and aws:SourceArn situation keys to the coverage for cover in opposition to the confused deputy downside: 
      "Situation": 
    "StringEquals": 
        "aws:SourceAccount": "your-account-id"
    ,
    "ArnLike": 
        "aws:SourceArn": "arn:aws:osis:area:your-account-id:pipeline/*"

    6. Map the OpenSearch Ingestion area function ARN as a backend person (as an all_access person) to the area person. We present a simplified instance to make use of the all_access function. For manufacturing situations, be certain to make use of a job with simply sufficient permissions to learn and write.
    7. Create an OpenSearch Serverless assortment, which is the place knowledge shall be ingested.
    8. Affiliate a knowledge coverage, as proven within the following code, to grant the OpenSearch Ingestion function permissions on the gathering: 
      [
  
    "Rules": [
      
        "Resource": [
          "index/collection-name/*"
        ],
        "Permission": [
          "aoss:CreateIndex",
          "aoss:UpdateIndex",
          "aoss:DescribeIndex",
          "aoss:WriteDocument",
        ],
        "ResourceType": "index"
      
    ],
    "Principal": [
      "arn:aws:iam::account-id:role/pipeline-role"
    ],
    "Description": "Pipeline function entry"
  
]

    9. If the gathering is outlined as a VPC assortment, you want to create a community coverage and configure it within the ingestion pipeline.

    Now you’re prepared to maneuver knowledge out of your provisioned area to OpenSearch Serverless.

    Transfer knowledge from provisioned domains to Serverless

    Setup Amazon OpenSearch Ingestion
    To get began, you could have an lively OpenSearch Service area (supply) and OpenSearch Serverless assortment (sink). Full the next steps to arrange an OpenSearch Ingestion pipeline for migration:

    1. On the OpenSearch Service console, select Pipeline underneath Ingestion within the navigation pane.
    2. Select Create a pipeline.
    3. For Pipeline title, enter a reputation (for instance, octank-migration).
    4. For Pipeline capability, you possibly can outline the minimal and most capability to scale up the sources. For now, you possibly can go away the default minimal as 1 and most as 4.
    5. For Configuration Blueprint, choose AWS-OpenSearchDataMigrationPipeline.
    6. Replace the next info for the supply:
      1. Uncomment hosts and specify the endpoint of the prevailing OpenSearch Service endpoint.
      2. Uncomment distribution_version in case your supply cluster is an OpenSearch Service cluster with compatibility mode enabled; in any other case, go away it commented.
      3. Uncomment indices, embrace, index_name_regex, and add an index title or sample that you simply wish to migrate (for instance, octank-iot-logs-2023.11.0*).
      4. Replace area underneath aws the place your supply area is (for instance, us-west-2).
      5. Replace sts_role_arn underneath aws to the function that has permission to learn knowledge from the OpenSearch Service area (for instance, arn:aws:iam::111122223333:function/osis-pipeline). This function needs to be added as a backend function inside the OpenSearch Service safety roles.
    7. Replace the next info for the sink:
      1. Uncomment hosts and specify the endpoint of the prevailing OpenSearch Serverless endpoint.
      2. Replace sts_role_arn underneath aws to the function that has permission to jot down knowledge into the OpenSearch Serverless assortment (for instance, arn:aws:iam::111122223333:function/osis-pipeline). This function needs to be added as a part of the information entry coverage within the OpenSearch Serverless assortment.
      3. Replace the serverless flag to be true.
      4. For index, you possibly can go away it as default, which is able to get the metadata from the supply index and write to the identical title within the vacation spot as of the sources. Alternatively, if you wish to have a unique index title on the vacation spot, modify this worth along with your desired title.
      5. For document_id, you will get the ID from the doc metadata within the supply and use the identical within the goal. Notice that customized doc IDs are supported just for the SEARCH kind of assortment; you probably have your assortment as TIMESERIES or VECTORSEARCH, you need to remark this line.
    8. Subsequent, you possibly can validate your pipeline to verify the connectivity of supply and sink to ensure the endpoint exists and is accessible.
    9. For Community settings, select your most popular setting:
      1. Select VPC entry and choose your VPC, subnet, and safety group to arrange the entry privately.
      2. Select Public to make use of public entry. AWS recommends that you simply use a VPC endpoint for all manufacturing workloads, however this walkthrough, choose Public.
    10. For Log Publishing Possibility, you possibly can both create a brand new Amazon CloudWatch group or use an present CloudWatch group to jot down the ingestion logs. This supplies entry to details about errors and warnings raised through the operation, which may also help throughout troubleshooting. For this walkthrough, select Create new group.
    11. Select Subsequent, and confirm the small print you specified to your pipeline settings.
    12. Select Create pipeline.

    It ought to take a few minutes to create the ingestion pipeline.
    The next graphic offers a fast demonstration of making the OpenSearch Ingestion pipeline by way of the previous steps.

    Confirm ingested knowledge within the goal OpenSearch Serverless assortment

    After the pipeline is created and lively, log in to OpenSearch Dashboards to your OpenSearch Serverless assortment and run the next command to record the indexes:

    GET _cat/indices?v

    The next graphic offers a fast demonstration of itemizing the indexes earlier than and after the pipeline turns into lively.

    Conclusion

    On this publish, we noticed how OpenSearch Ingestion can ingest knowledge into an OpenSearch Serverless assortment with out the necessity to use the third-party options. With minimal knowledge producer configuration, it routinely ingested knowledge to the gathering. OSI additionally permits you to remodel or reindex the information from ES7.x model earlier than ingestion to an OpenSearch Service area or OpenSearch Serverless assortment. OSI eliminates the necessity to provision, scale, or handle servers. AWS provides numerous sources so that you can shortly begin constructing pipelines utilizing OpenSearch Ingestion. You should use numerous built-in pipeline integrations to shortly ingest knowledge from Amazon DynamoDB, Amazon Managed Streaming for Apache Kafka (Amazon MSK), Amazon Safety Lake, Fluent Bit, and lots of extra.
