Amazon OpenSearch Service now supports Graviton4 based (c8g,m8g,r8g and r8gd) instances

Amazon OpenSearch Service now supports latest generation Graviton4-based Amazon EC2 instance families. These new instance types are compute optimized (C8g), general purpose (M8g), and memory optimized (R8g, R8gd) instances. AWS Graviton4 processors provide up to 30% better performance than AWS Graviton3 processors with c8g, m8g and r8g & r8gd offering the best price performance for compute-intensive, general purpose, and memory-intensive workloads respectively.
