How to consolidate cross-Region S3 data into OpenSearch

This article explains how to use Amazon OpenSearch Ingestion to consolidate S3 data from multiple AWS Regions into a single OpenSearch domain or collection.

• OpenSearch Ingestion now supports cross-Region S3 bucket ingestion for unified analytics
• Two approaches: batch processing using S3 scan, or streaming via SQS queues
• Batch scenario: pipeline reads from S3 buckets in different Regions directly
• Streaming scenario: uses SNS topics and SQS queues to consolidate AWS vended logs
• Requires s3:GetBucketLocation IAM permission for cross-Region functionality
• Pipeline uses AWS STS tokens to access buckets in their respective Regions
• Console blueprints available for common vended log types like VPC Flow Logs
• Also supports cross-account access with additional IAM permissions

The feature simplifies consolidating multi-Region data into a single OpenSearch instance for centralized search and analytics.
