Elasticsearch JVM Monitoring: G1GC and Elasticsearch APIs

AI Impact Summary

Elasticsearch 6.4 and later utilizes the G1 garbage collector, a significant shift from the CMS collector previously used. This change addresses performance concerns around long GC pauses, particularly when dealing with large datasets and complex queries. Monitoring JVM memory usage, including heap size and GC activity, is crucial for troubleshooting performance bottlenecks and ensuring Elasticsearch stability, leveraging the node info and node statistics APIs for detailed insights.
