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

Stipulations

Be sure to meet the next stipulations:

Create an SQS queue

Amazon SQS provides a safe, sturdy, and accessible hosted queue that permits you to combine and decouple distributed software program techniques and elements. Create a normal SQS queue and supply a descriptive title for the queue, then replace the entry coverage by navigating to the Amazon SQS console, opening the main points of your queue, and enhancing the coverage on the Superior tab.

The next is a pattern entry coverage you may 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 should utilize Amazon EventBridge.

Create an S3 bucket and allow Amazon S3 occasion notification

Create an S3 bucket that would be the supply for CSV information and allow Amazon S3 notifications. The Amazon S3 notification invokes an motion in response to a particular occasion within the bucket. On this workflow, at any time when there in an occasion of sort S3:ObjectCreated:*, the occasion sends an Amazon S3 notification to the SQS queue created within the earlier step. Check with Walkthrough: Configuring a bucket for notifications (SNS matter 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
