OpenSearch Ingestion uses Data Prepper, an open-source component, to collect, transform, and route data to OpenSearch domains. The video explains the benefits of setting up data pipelines, including cost savings, improved data quality, and enhanced privacy controls. Towery describes how OpenSearch Ingestion supports log, trace, and metric data pipelines, and integrates with various open-source projects.
