[](https://opensearch.org) # OpenSearch AWS Sigv4 Client The `opensearch-aws-sigv4` library provides an AWS Sigv4 client for connecting to [Amazon OpenSearch Service](https://docs.aws.amazon.com/opensearch-service/index.html). This library is an AWS Sigv4 wrapper for [`opensearch-ruby`](https://github.com/opensearch-project/opensearch-ruby/tree/main), which is a Ruby client for OpenSearch. The `OpenSearch::Aws::Sigv4Client`, therefore, has all features of `OpenSearch::Client`. ## Compatibility The `opensearch-aws-sigv4` library is compatible with all versions of `opensearch-ruby`. ## User Guide See [USER_GUIDE](USER_GUIDE.md). ## License This software is licensed under the [Apache 2 license](LICENSE).
