Overview
...
Errors during 20 users - non-Eureka test are due to a very high load for the OpenSearch cluster. For this test we have a throughput of about 55 ops/s and the maximal Elastic Search throughput is 52 search operations (https://repost.aws/knowledge-center/opensearch-resolve-429-error) according to our claster cluster configurations.
Use the following formula to calculate maximum active threads for search requests:int ((# of available_processors * 3) / 2) + 1.- For an r6g.2xlarge.search node, you can perform a maximum of 13 search operations:
(8 VCPUs * 3) / 2 + 1 = 13 operations - For an OpenSearch Service cluster with four nodes, you can perform a maximum of 52 search operations:
4 nodes * 13 = 52 operations
