OpenSearch Ingestion makes use of pipelines as a mechanism that consists of three main elements:

Supply – The enter element of a pipeline. It defines the mechanism by way of which a pipeline consumes data.
Processors – The intermediate processing items that may filter, remodel, and enrich data right into a desired format earlier than publishing them to the sink. The processor is an elective element of a pipeline.
Sink – The output element of a pipeline. It defines a number of locations to which a pipeline publishes data. A sink will also be one other pipeline, which lets you chain a number of pipelines collectively.

You may course of knowledge recordsdata written in S3 buckets in two methods: by processing the recordsdata written to Amazon S3 in close to actual time utilizing Amazon Easy Queue Service (Amazon SQS), or with the scheduled scans strategy, wherein you course of the information recordsdata in batches utilizing one-time or recurring scheduled scan configurations.

Within the following part, we offer an outline of the answer and information you thru the steps to ingest CSV recordsdata from Amazon S3 into OpenSearch Service utilizing the S3-SQS strategy in OpenSearch Ingestion. Moreover, we exhibit learn how to visualize the ingested knowledge utilizing OpenSearch Dashboards.

Answer overview

The next diagram outlines the workflow of ingesting CSV recordsdata from Amazon S3 into OpenSearch Service.

The workflow includes the next steps:

The person uploads CSV recordsdata into Amazon S3 utilizing strategies comparable to direct add on the AWS Administration Console or AWS Command Line Interface (AWS CLI), or by way of the Amazon S3 SDK.
Amazon SQS receives an Amazon S3 occasion notification as a JSON file with metadata such because the S3 bucket identify, object key, and timestamp.
The OpenSearch Ingestion pipeline receives the message from Amazon SQS, masses the recordsdata from Amazon S3, and parses the CSV knowledge from the message into columns. It then creates an index within the OpenSearch Service area and provides the information to the index.
Lastly, you create an index sample and visualize the ingested knowledge utilizing OpenSearch Dashboards.

OpenSearch Ingestion offers a serverless ingestion framework to effortlessly ingest knowledge into OpenSearch Service with just some clicks.

Conditions

Ensure you meet the next conditions:

Create an SQS queue

Amazon SQS affords a safe, sturdy, and out there hosted queue that allows you to combine and decouple distributed software program techniques and elements. Create a normal SQS queue and supply a descriptive identify for the queue, then replace the entry coverage by navigating to the Amazon SQS console, opening the small print of your queue, and modifying the coverage on the Superior tab.

The next is a pattern entry coverage you might use for reference to replace the entry coverage:

{
  "Model": "2008-10-17",
  "Id": "example-ID",
  "Assertion": [
    {
      "Sid": "example-statement-ID",
      "Effect": "Allow",
      "Principal": {
        "Service": "s3.amazonaws.com"
      },
      "Action": "SQS:SendMessage",
      "Resource": "<SQS_QUEUE_ARN>"
    }
  ]
}

SQS FIFO (First-In-First-Out) queues aren’t supported as an Amazon S3 occasion notification vacation spot. To ship a notification for an Amazon S3 occasion to an SQS FIFO queue, you need to use Amazon EventBridge.

Create an S3 bucket and allow Amazon S3 occasion notification

Create an S3 bucket that would be the supply for CSV recordsdata and allow Amazon S3 notifications. The Amazon S3 notification invokes an motion in response to a particular occasion within the bucket. On this workflow, every time there in an occasion of sort S3:ObjectCreated:*, the occasion sends an Amazon S3 notification to the SQS queue created within the earlier step. Confer with Walkthrough: Configuring a bucket for notifications (SNS subject or SQS queue) to configure the Amazon S3 notification in your S3 bucket.

Create an IAM coverage for the OpenSearch Ingest pipeline

Create an AWS Identification and Entry Administration (IAM) coverage for the OpenSearch pipeline with the next permissions:

Learn and delete rights on Amazon SQS
GetObject rights on Amazon S3
Describe area and ESHttp rights in your OpenSearch Service area

The next is an instance coverage:

{
  "Model": "2012-10-17",
  "Assertion": [
    {
      "Effect": "Allow",
      "Action": "es:DescribeDomain",
      "Resource": "<OPENSEARCH_SERVICE_DOMAIN_ENDPOINT>:domain/*"
    },
    {
      "Effect": "Allow",
      "Action": "es:ESHttp*",
      "Resource": "<OPENSEARCH_SERVICE_DOMAIN_ENDPOINT>/*"
    },
    {
      "Effect": "Allow",

    {
      "Effect": "Allow",
      "Action": [
        "sqs:DeleteMessage",
        "sqs:ReceiveMessage"
      ],
      "Useful resource": "<SQS_QUEUE_ARN>"
    }
  ]
}

Create an IAM function and connect the IAM coverage

A belief relationship defines which entities (comparable to AWS accounts, IAM customers, roles, or companies) are allowed to imagine a specific IAM function. Create an IAM function for the OpenSearch Ingestion pipeline (osis-pipelines.amazonaws.com), connect the IAM coverage created within the earlier step, and add the belief relationship to permit OpenSearch Ingestion pipelines to write down to domains.

Configure an OpenSearch Ingestion pipeline

A pipeline is the mechanism that OpenSearch Ingestion makes use of to maneuver knowledge from its supply (the place the information comes from) to its sink (the place the information goes). OpenSearch Ingestion offers out-of-the-box configuration blueprints that can assist you rapidly arrange pipelines with out having to creator a configuration from scratch. Arrange the S3 bucket because the supply and OpenSearch Service area because the sink within the OpenSearch Ingestion pipeline with the next blueprint:

    - date:
        match:
          - key: order_date
            patterns:
              - MM/dd/yyyy
        vacation spot: order_date_new
  sink:
    - opensearch:
        hosts:
          - <OPEN_SEARCH_SERVICE_DOMAIN_ENDPOINT>
        index: csv-ingest-index
        aws:
          sts_role_arn: <STS_ROLE_ARN>
          area: <AWS_REGION>

On the OpenSearch Service console, create a pipeline with the identify my-pipeline. Preserve the default capability settings and enter the previous pipeline configuration within the Pipeline configuration part.

Replace the configuration setting with the beforehand created IAM roles to learn from Amazon S3 and write into OpenSearch Service, the SQS queue URL, and the OpenSearch Service area endpoint.
