CloudWatch Logs Insights Adds JOIN and Sub-query Support
🔎 Amazon has added JOIN and sub-query commands to CloudWatch Logs Insights, enabling queries that span multiple log groups and correlate data from different sources. The new capabilities remove the need to run separate queries and manually merge results, accelerating troubleshooting and investigations. Typical uses include correlating application and infrastructure errors, analyzing security events across services, and tracking user sessions across distributed systems. The features are available today in all commercial AWS Regions.
