The Logs IA tier targets cost-effective storage for logs accessed occasionally, such as forensic or troubleshooting data. AWS expanded query capabilities to include OpenSearch’s Piped Processing Language (PPL) and SQL, providing advanced log analytics beyond the existing Logs Insights language.
Data protection features now enable automatic detection and masking of sensitive information in logs, helping meet compliance requirements. These improvements facilitate secure, flexible analysis of less-frequently accessed logs, complementing prior features like export to S3 and encryption while reducing ingestion costs.
