Joaquin Rios updated the DataDog/documentation repository to reflect AWS CloudWatch Metric Streams regional availability in the us3 region. He focused on enhancing documentation by modifying the site-region shortcode in two Markdown files, ensuring that customers deploying Metric Streams with Kinesis Data Firehose receive accurate, region-specific guidance. Joaquin’s work centered on documentation best practices, using Markdown to clearly communicate new regional support and reduce onboarding friction for users. The update addressed the need for precise, up-to-date information as DataDog expanded its regional offerings. Over the month, Joaquin delivered one targeted feature, demonstrating depth in technical writing and documentation maintenance.
