Contributed a documentation enhancement to the opensearch-project/data-prepper repository, focusing on the OpenSearch plugin’s integration with MSK. Developed a comprehensive example in Markdown that demonstrates configuring a data ingestion pipeline, highlighting the use of data processing techniques such as timestamp parsing and dynamic, date-based index naming. This update clarifies operational behavior for users by detailing how to construct indices based on event timestamps, thereby improving the reliability of data flows from MSK to OpenSearch. The work streamlines onboarding for new users and supports maintainability by providing clear, actionable guidance on leveraging OpenSearch and data processing within real-world workflows.
