Amazon OpenSearch Service now lets you provision up to 16,000 IOPS and 1000 MiB/s throughput for every 3 TiB gp3 volume size provisioned per data node, enabling you to achieve better search and indexing performance.

Previously, customers were allowed to provision a maximum of 16,000 IOPS and up to 1000 MiB/s throughput per data node for their gp3 volume type, irrespective of the provisioned volume size. These provisioning limits worked for the majority of workloads. However, a few workloads, especially those with large data volumes or high search traffic, required the ability to provision higher IOPS and throughput to address their performance bottlenecks. Now, you can provision up to 16,000 IOPS and 1000 MiB/s throughput for every 3 TiB volume size provisioned per data node. Please note that your instance type can limit the maximum IOPS and throughput provisioning. You can check the maximum limits supported for an instance type in the EBS documentation.

The increased IOPS and throughput limits for gp3 volumes are now available on Amazon OpenSearch Service domains in all AWS regions globally where Amazon OpenSearch service is available. Please refer to the AWS Region Table for more information about Amazon OpenSearch Service.
