AWS OpenSearch Ingestion Adds Confluent Blueprint, w/Pipeline Ex.

This post details the technical integration between Amazon OpenSearch Ingestion and Confluent Cloud, specifically focusing on private connectivity using AWS PrivateLink and Elastic Network Interfaces (xENIs). It explains the networking challenges of unidirectional traffic in PrivateLink and how xENIs enable OpenSearch Ingestion to connect to third-party private data sources like Confluent Cloud. The post also covers authentication mechanisms (SASL/PLAIN with API keys for Confluent, IAM roles for OpenSearch) and scaling considerations based on OpenSearch Capacity Units (OCUs) and Kafka partitions. A step-by-step guide for configuring the OpenSearch Ingestion pipeline using a Confluent blueprint is provided, including details on secrets management and network configuration.
