+We are excited to announce the release of the new OpenSearch-Hadoop connector. This tool enables efficient interaction between your Hadoop-based Big Data operations and OpenSearch clusters, supporting all versions of OpenSearch.
+
+## OpenSearch-Hadoop connector features:
+
+- **Versatility**: Compatible with Scala up to version 2.13.x and Spark up to version 3.2.x, the connector facilitates data processing and analysis operations across different environments.
+- **Memory and I/O Efficient**: The connector is designed with a focus on performance. It uses pull-based parsing, supports bulk updates, and direct conversion to/of native types, resulting in efficient memory and network I/O usage.
+- **Adaptive I/O**: The connector can detect transport errors and retry automatically. In case of node failures, it can re-route requests to available nodes. If OpenSearch is overloaded, the connector can detect data rejection and resend it.
+- **Facilitates Data Co-Location**: The connector integrates with Hadoop to expose network access information, enabling co-located OpenSearch and Hadoop clusters to be aware of each other, thus reducing network I/O.
+- **Secure Access**: Supports IAM for AWS-managed OpenSearch, ensuring secure access to your AWS resources.
